Abstract
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.
