SYSTEM AND METHOD OF TRANSMITTING AND RECEIVING AN OFDM SIGNAL WITH REDUCED PEAK -TO -AVERAGE POWER RATIO USING DUMMY SEQUENCE INSERTATION

摘要

A method transmits data by generating (110-i) a plurality of candidate orthogonal frequency division multiplex (OFDM) signals, selecting. (120) the candidate OFDM signal that has the lowest peak- to-average-power ratio, and transmitting (130) the selected OFDM signal. Each of the candidate OFDM signals is generated by inserting (112) a set of one or more dummy bits before a data bit sequence to produce an input bit sequence, recursively convolutionally encoding (114) the input bit sequence to generate an encoded bit sequence, interleaving- (166) the encoded. bit sequence, and OFDM modulating (118) the interleaved, encoded bit sequence to generate the candidate OFDM signal. The set of one or more dummy bits for each of the candidate OFDM signals is different than the set of one or more dummy bits for each of the other candidate OFDM signals.
