Patent number: 8964716Abstract: A method of transmitting an RF signal over a wireless communication network is provided. The method comprises determining a respective weighting factor for each of a plurality of digital signals each corresponding to a respective channel, the weighting factors weighting the digital signals to produce a composite signal intended for transmission as an RF signal via a power amplifier. The method further comprises executing instructions on a processor to dynamically calculate a metric related to the non-linearity of the power amplifier's transfer characteristics for the composite signal using the determined weighting factors. The method further comprises supplying to the power amplifier a signal for transmission as an RF signal and amplifying the signal for transmission at the power amplifier to transmit an RF signal over the wireless communication network via at least one antenna. The method further comprises controlling the transmission based on the metric related to the amplifier non-linearity.Type: GrantFiled: May 26, 2009Date of Patent: February 24, 2015Assignee: Icera Inc.Inventors: Phil Jones, Carlo Luschi, Abdelkader Medles, Donal Price

Patent number: 8654662Abstract: There is disclosed a method of determining one or more candidate frequencies for a carrier signal in a received signal, which method comprises: generating a narrowband spectrum of the received signal; detecting one or more peaks in the narrowband spectrum; generating a candidate frequency list, each frequency at which a peak occurs being included in the candidate frequency list. The method further comprises: removing the detected one or more peaks from the narrowband spectrum to generate a modified narrowband spectrum; detecting one or more further peaks in the modified narrowband spectrum; and modifying the candidate frequency list in dependence on the one or more further peaks.Type: GrantFiled: December 11, 2008Date of Patent: February 18, 2014Assignee: ICERA, Inc.Inventors: Steve Allpress, Laolu Lijofi, Donal Price

Patent number: 8254405Abstract: A method, program and apparatus for transmitting a signal in a time slot of a channel comprising a plurality of time slots. Using a transmitter having a processor and a power amplifier, the method comprises: retrieving a reference ramp pattern from a memory; determining an output power level for the slot from a plurality of possible output power levels, each requiring a respective corresponding ramp pattern; executing software on the processor to apply a scaling function to the reference ramp pattern in dependence on the determined output power level, thus generating a scaled ramp pattern corresponding to the pattern required for that determined level; supplying the scaled ramp pattern to a control input of the power amplifier, to control the gain of the power amplifier during the time slot; and using the power amplifier, controlled according to the scaled ramp pattern, to transmit the signal in the time slot.Type: GrantFiled: February 10, 2010Date of Patent: August 28, 2012Assignee: ICERA Inc.Inventor: Donal Price

Publication number: 20110182197Abstract: A method, program and apparatus for transmitting an RF signal over a wireless communication network. The method comprises: determining a respective weighting factor for each of a plurality of digital signals each corresponding to a respective channel, the weighting factors being for weighting the digital signals for combination to produce a composite signal intended for transmission as an RF signal via a power amplifier. The method further comprises: executing instructions on a processor to dynamically calculate, in the processor, a metric related to the non-linearity of the power amplifier's transfer characteristics for the composite signal using the determined weighting factors; supplying to the power amplifier a signal for transmission as an RF signal; amplifying the signal for transmission at the power amplifier to transmit an RF signal over the wireless communication network via at least one antenna; and controlling the transmission based on the metric related to the amplifier non-linearity.Type: ApplicationFiled: May 26, 2009Publication date: July 28, 2011Applicant: ICERA INC.Inventors: Phil Jones, Carlo Luschi, Abdelkader Medles, Donal Price
