摘要： 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.

摘要： 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.

摘要： 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.
