Abstract :
In this paper, an enhanced orthogonal frequency division multiplexing (OFDM) with offset quadrature amplitude modulation (OQAM) system utilising Walsh-Hadamard transform (WHT) is presented. This system demonstrates high resistance to the multipath transmission. The simulation results over standard ITU channels for pedestrian and vehicular confirm the improvement of the proposed system over the conventional OFDM and OFDM/OQAM systems by approximately 6 dB in terms of Eb/No at 10-3 of bit error rate (BER). Furthermore, the computational complexity is reduced by 50% for the integration of the WHT in the system.
