Patent ID: 7961591

Claim:
A method of transmitting an orthogonal frequency division multiplexing (OFDM) signal, comprising: receiving a group of input symbols based on which the transmitted signal is to be generated; selecting, from among a plurality of available allocations of input symbols to sub-carriers, one allocation to apply to the received group of input symbols, each said available allocation serving to allocate the input symbols to respective sub-carriers in a different way from each other available allocation, and the allocation selection being based on predicted values of a predetermined property of the transmitted signal for different available allocations; and generating the transmitted signal using the selected allocation wherein the generation of the transmitted signal also involves applying further processing, in addition to selecting one allocation, to control said predetermined property of the transmitted signal; and wherein said further processing is selected from processing options including selected mapping (SLM) processing, partial transmit sequence (PTS) processing, and tone reservation (TR) processing, based on the predicted values of the predetermined property for each of the processing options if used to generate the transmission signal using the selected allocations.
