Abstract :
The adapted orthogonal frequency division multiplexing (OFDM) termed as fast-OFDM system and overlapping multi-carrier code division multiple access systems (overlapping multi-carrier direct-sequence CDMA and overlapping multi-tone CDMA) are compared. The effect of the sub-carriers overlapping, in additive white Gaussian noise AWGN, is investigated for binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK). The results show that the system performance of an overlapping multicarrier-CDMA is comparable to that of fast-OFDM system in the presence of AWGN and inter-carrier interference when a conventional matched filter receiver is used.
