Abstract :
Some results of PAR reduction in OFDM signals and error correction capabilities by using complementary Golay sequences are presented. This results have been obtained by simulations and later we have implemented this technique in a DSP. Simulation results show a PAR of 3 dB; however, physical results produce a PAR of 6 dB. Also, an algorithm for generation of Golay base sequences on the fly is proposed.
