Abstract :
This paper investigates the Golay complementary sequences in a WHT-OFDM system with BPSK modulation. By examining and exploiting the property of the aperiodic cross-correlation between Walsh-Hadamard sequences, we classify and enumerate the binary WHT-OFDM Golay sequences. As with OFDM, the Golay sequences in WHT-OFDM are also composed of some certain cosets of first order Reed-Muller codes within the second order Reed-Muller codes. We show that a WHT-OFDM system has more Golay complementary sequences than an OFDM system
