Abstract:
1. A method of transmitting an RF signal over a wireless communication network, the method comprising: 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; 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 said metric related to the amplifier non-linearity; wherein said communication network operates according to a set of scrambling codes, and the processor is programmed to perform said dynamic calculation by dynamically evaluating an expression that comprises moments of some combinations of the scrambling codes.
