Patent number: 7173944Abstract: A digital subscriber line (DSL) communication system that utilizes the high frequency band of a standard telephone line does not require the use of a plain old telephone service (POTS) splitter in the resident's home, which provided isolation between the POTS frequency band (0 to 4 kHz) and the DSL frequency band. A digital subscriber line modem utilizes either constant envelope modulation or quadrature amplitude modulation for outputting DSL signals upstream to a central office. When a telephone in the resident's home is detected as being off-hook, then the constant envelope modulation is used by the DSL modem in order to lessen the intermodulation product distortion that results in audible noise heard by a user of the telephone. When the telephone is on-hook, then another type of modulation, such as QAM, is used to maximize the upstream data rate capability in the DSL frequency band, since any noise generated by the QAM is not a problem due to the non-use of the POTS frequency band.Type: GrantFiled: April 11, 2000Date of Patent: February 6, 2007Assignee: Conexant Systems, Inc.Inventors: Kenneth D. Ko, David O. Anderton, Ismail I. Eldumiati, Steven A. Gronemeyer, Don L. Harmer, P. Michael Henderson, Joel D. Peshkin, Raphael Rahamim, Frederic M. Stubbe, John S. Walley, Kenneth S.

Patent number: 7027788Abstract: A system for receiving a signal is provided. The system includes a receiver that is operable to receive the signal, but which may also receive a noise signal. A duty cycle system is connected to the receiver. The duty cycle system can turn the receiver off and on at a controllable frequency. A signal strength system is also connected to the receiver, and is further connected to the duty cycle system. The signal strength system can determine the signal strength of the signal received by the receiver. If the signal strength indicates that the noise signal is not being received, the signal strength system generates control commands to the duty cycle system that cause the duty cycle system to cycle various components of the receiver that are used to suppress noise on and off, so as to conserve power.Type: GrantFiled: December 26, 2001Date of Patent: April 11, 2006Assignee: Skyworks Solutions, Inc.Inventor: Kenneth S.

Publication number: 20030058929Abstract: The present invention provides a method and apparatus for adaptive processing in a communication system receiver. The adaptive processing facilitates power savings and permits enhanced performance when necessary. This extends a receiver's operation time in receivers that operate on batteries, such as in cordless telephones or cellular telephones. A receiver adopting the principles of the present invention evaluates the characteristics and dynamics of an incoming signal, and based on the quality of the incoming signal, adjusts various aspects of the receiver such as the on-time correlators and analog to digital converters, the timing circuits, the despread equalizers, and the combiner. If the receiver comprises a receiver operation in accordance with GSM, the receiver may cycle the MLSE detection algorithms or cross correlation may be done over fewer data symbols.Type: ApplicationFiled: September 30, 1998Publication date: March 27, 2003Inventors: EARL C.

Digital signal processing techniques are utilized to adapt to varying subscriber line conditions due to POTS telephone equipment. The digital signal processing techniques eliminate the need for a splitter by reducing susceptibility to distortion due to varying subscriber line characteristics. The digital subscriber line modem utilizes constant envelope modulated signals and frequency division multiplexing, where the constant envelope modulations lessens the intermodulation distortion products due to DSL signals that are transmitted by the modem and which may result in audible noise at the POTS telephone equipment due to non-linearities of the POTS telephone equipment.Type: GrantFiled: December 2, 1997Date of Patent: April 3, 2001Assignee: Conexant Systems, Inc.Inventors: Kenneth D.

Patent number: 6184696Abstract: The described method and apparatus wirelessly test individual integrated circuit die on a wafer containing multiple die. The method incorporates activating a selected die on the wafer by wirelessly impacting the die with at least two beams of electromagnetic radiation so that the die receives radiation energy having at least a first energy level, thereby activating the die by causing a current to flow in the die. Each beam of electromagnetic energy individually has less than the first energy level required to activate the die. The beams of electromagnetic energy are directed so that they at least partially overlap on the selected die. In the region of overlap, the two beams together impact the die with an energy level at least equal to the first energy level required to activate the die. The method may additionally include detecting electromagnetic radiation emitted by the die in response to the electromagnetic energy received from the beams of electromagnetic energy.Type: GrantFiled: March 23, 1998Date of Patent: February 6, 2001Assignee: Conexant Systems, Inc.Inventors: Stanley A.

Patent number: 6181674Abstract: A unique system for efficiently implementing filtered, phase shifted channels is disclosed. Instead of using separate transmit shaping filters for each channel, and modulating the filtered signals with phase-shifted carrier and one might suppose, the system phase rotates the signals for each channel and modulates such phase rotated signals with a single carrier. In addition, the system decomposes the phase rotations into 90° pre-filter portions and a post-filter portion of, for example, 45°. In an 8 channel system, such as proposed in the IS-95B standard, the channels are divided into two groups and the 90° phase rotations for each group are done at the input of the transmit shaping filters. A 45° phase rotation is then done for one of the groups at the output of the transmit shaping filter. Significantly, no multiplication is required.Type: GrantFiled: September 30, 1998Date of Patent: January 30, 2001Assignee: Conexant Systems, Inc.Inventors: Weizhuang Xin, Ganning Yang, Kenneth S.
