Abstract:
1. A method of processing data for transmission to a remote device via a wireless network, the method comprising: generating an input data block for a selected number of subcarrier frequencies for input to an OFDM modulator, wherein a size of the OFDM modulator exceeds the selected number of subcarrier frequencies; padding the input data block to generate an expanded data block having a size matched to the size of the OFDM modulator; modulating the expanded data block to generate a modulated symbol stream; filtering the modulated symbol stream with a variable filter; configuring one or more filter properties for the variable filter based on the selected number of subcarrier frequencies; and pre-compensating at least one of an amplitude and phase of one or more values in the input data block to correct at least one of an amplitude error and a phase error introduced by the filtering step.
