Abstract :
Based on the properties of wavelet orthogonal basis, three novel wavelet-based multi-carrier CDMA (MC-CDMA) systems are proposed, and their advantages and performances are investigated by the comparison with the conventional MC-CDMA systems. For the additive white Gaussian noise (AWGN) channel, all three wavelet-based MC-CDMA systems possess the same bit error rates as the corresponding MC/BPSK-CDMA and MC/QPSK-CDMA systems, but have significant higher bandwidth efficiency than the conventional MC-CDMA systems by the suitable choice of wavelet functions. Their potential applications in the broadband wireless communications to improve bandwidth efficiency and combat the fading and narrowband interference are also discussed
