Abstract :
Orthogonal Frequency Division Multiplexing (OFDM) is an excellent choice of high speed data transmission systems. Since a large number of subcarriers uses in most of the broadband data communications standards, high PAPR is also a great drawbacks. On the other hand, subcarriers orthogonality is very sensitive to carrier frequency offset (CFO) in between transmitter and receiver oscillators. Golay complementary sequences (Coset Representatives) with Reed-Muller code gives maximum 3 dB PMEPR [20] and reduces ICI, due to the CFO, significantly [1]. In this work, our contributions are two-fold: 1) we obtain all, total 1024, possible coset representatives for 32 subcarriesrs BPSK modulated Coded-OFDM (COFDM), 2) we simulated maximum Peak Envelope Power (PEP) and Inter-carrier Interference (ICI) over each coset representatives.
