Patent number: 7181184Abstract: A band edge amplitude reduction system changes the filtering characteristics of a receiver based on the amplitude of signal(s) adjacent to an edge of the operating band of the receiver and/or of signals not under the power control of the receiver. For example, the receiver measures the power level over a bandwidth at the band edges of the operating band of the receiver. If the signals adjacent to the operating band are strong enough relative to the signal power within the operating band, overload protection circuitry changes the filtering characteristics of the receiver to improve the attenuation of the signal(s) from the adjacent band(s). In certain embodiments, the overload protection circuitry switches in filter(s) with a narrower bandwidth to attenuate the signal(s) from adjacent band(s) at the edge(s) of the operating band of the receiver, thereby preventing interference with or the overload of the receiver by signals from outside the operating band and/or not under the power control of the receiver.Type: GrantFiled: August 22, 2000Date of Patent: February 20, 2007Assignee: Lucent Technologies Inc.Inventors: Richard W Dimeo, Arild Kolsrud, Sanjay Kumar, Carmine James Pagano, II

Patent number: 7064613Abstract: An amplifier bias system and method has only reduced resonances at least throughout the envelope frequency of the signal to be amplified. Thus, the amplifier bias system can provide bias current to the amplifier with minimal voltage variations over the envelope frequency band, especially during signal peaks. For example, the amplifier bias system can be used as an amplifier gate or drain bias network where the amplifier bias system is coupled between the power supply and the gate or drain terminals of the amplifier. The amplifier bias system can include an amplifier bias filter having an impedance which is relatively low at least throughout the envelope frequency of the input signal and relatively high at radio frequency.Type: GrantFiled: March 25, 2002Date of Patent: June 20, 2006Assignee: Lucent Technologies Inc.Inventors: Arild Kolsrud, Norman Gerard Ziesse

Patent number: 7039386Abstract: In the method, an emergency broadcast station receives report of an impending or current disaster-related situation from a local authority. The geographic area to be affected by the impending or current disaster-related situation is served by an existing communication system, such as a cellular network. The emergency broadcast station generates a signal representing an emergency broadcast message that contains a frequency of an accessible main emergency channel at the emergency broadcast station, and a priority level classifying the emergent or impending disaster-related situation. The signal is transmitted to one or base stations, each serving a plurality of users of the system, which in turn send the signal to the users. The users tune to the frequency of the channel to receive the emergency broadcast message.Type: GrantFiled: April 18, 2002Date of Patent: May 2, 2006Assignee: Lucent Technologies Inc.Inventor: Arild Kolsrud

Patent number: 6944238Abstract: A digital transmitter converts a digital signal into analog form with a digital to analog converter (DAC) and uses an analog signal image produced from the DAC to provide an analog signal at a transmission frequency and/or uses a projected analog signal image to produce analog signals for transmission. Rather than removing analog signal images with a low pass filter at the output of the DAC and/or using analog signal images and analog mixers for frequency conversion, the digital transmitter uses the analog signal images from the DAC to produce the analog signals at the desired frequency/frequencies. By setting and/or adjusting the conversion rate for the DAC and/or the digital signal frequency/frequencies, the analog signal images produced from the DAC can be positioned in the desired frequency band(s). For example, the digital transmitter can position the digital signals within non-overlapping portions of a conversion bandwidth defined as one-half the conversion rate for the DAC.Type: GrantFiled: February 16, 2001Date of Patent: September 13, 2005Assignee: Lucent Technologies Inc.Inventors: Julio Antonio Garceran, Walter Joseph Kaminski, Arild Kolsrud

Patent number: 6678512Abstract: A receiver receives analog signals at radio frequency (RF), and the RF analog signals are converted into the digital domain. As such, the receiver does not require frequency conversion stage(s) prior to analog to digital conversion. For example, the receiver can comprise at least one antenna(s) which receives radio frequency (RF) analog signals at different frequency bands. The analog RF signals are provided to a single analog to digital (A/D) converter, and the A/D converter converts the analog RF signals at the different frequency bands into digital signals within the Nyquist bandwidth. By properly selecting the sampling rate of the A/D converter for the RF analog signals, the A/D converter can produce replicas of the different frequency bands of the analog signals in non-overlapping portions of the Nyquist bandwidth.Type: GrantFiled: April 14, 2000Date of Patent: January 13, 2004Assignee: Lucent Technologies Inc.Inventors: Walter Joseph Kaminski, Arild Kolsrud

Patent number: 6574459Abstract: A receiver provides received analog signals to a plurality of channel branches, and on at least one of the channel branches, the frequency of the received analog signals is adjusted independent of the relative positions of the corresponding analog signals in the radio frequency (RF) spectrum. The analog signals on the channel branches are then combined, and the combined analog signals are converted into the digital domain. For example, the receiver comprises at least one antenna(s) which receives radio frequency (RF) analog signals. A channel branch arranger receives the analog RF signals from the antenna(s) and provides the RF analog signals to a plurality of channel branches.Type: GrantFiled: April 14, 2000Date of Patent: June 3, 2003Assignee: Lucent Technologies Inc.Inventors: Walter Joseph Kaminski, Arild Kolsrud

Patent number: 6542101Abstract: An analog to digital conversion (A/D) system produces a corrected output of an analog to digital (A/D) converter using at least one past signal sample. For example, the A/D system estimates a reference value or point, such as a reference amplitude, for the at least one past sample. In response to an indication that the A/D converter is saturated, the A/D system uses the reference value to predict a next reference value, such as a next amplitude value, from which a corrected digital sample value is produced to replace the saturating sample.Type: GrantFiled: July 14, 2000Date of Patent: April 1, 2003Assignee: Lucent Technologies Inc.Inventor: Arild Kolsrud

Patent number: 6515599Abstract: The high-power selective signal attenuator includes an attenuator attenuating analog main signals, and a first analog-to-digital converter converting output of the attenuator to digital. A digital-to-analog converter reconverts the digital output of the first ADC to analog, and a cancellor receives the main signals and the analog output from the DAC. The cancellor cancels the analog output of the DAC from the main signals to substantially eliminate high-power signals. A second ADC receives the output of the cancellor and generates a digital output. Based on the digital output, control circuitry dynamically controls the attenuation of the attenuator to prevent saturation of the second ADC and to improve information throughput.Type: GrantFiled: March 22, 2000Date of Patent: February 4, 2003Assignee: Lucent Technologies Inc.Inventors: Arild Kolsrud, Christopher F.

Patent number: 6377196Abstract: An analog-to-digital (A/D) converter system which converts an attenuated analog input signal into a digital value and shifts the position of the digital value within the digital output depending on the attenuation of the analog input signal. For example, in response to an analog input signal which saturates a first A/D converter, a second A/D converter receives and converts an attenuated analog input signal, and the output of the second A/D converter is used to produce the more significant bits of the digital output value to convert a higher amplitude range (power or voltage level range) for the analog input signal. In another example, a level detector can detect the amplitude of the analog input signal and provide an indication of the amplitude of the analog input signal. In response, the analog input signal is attenuated and provided to an A/D converter.Type: GrantFiled: July 14, 2000Date of Patent: April 23, 2002Assignee: Lucent Technologies Inc.Inventors: Arild Kolsrud, Carmine James Pagano, II
