Convolutionally coded overlapping multicarrier DS/CDMA systems with arbitrary chip waveforms

In this paper, we consider convolutionally coded multi-carrier DS/CDMA systems using overlapping subchannels in time-limited and band-limited channels, and analyze their performance when arbitrary chip waveform and random binary signature sequences are used. It is shown that the proposed system, the convolutionally coded overlapping multi-carrier DS/CDMA system with a symbol mapping method utilizing diversity, outperforms the conventional convolutionally coded systems. It is also shown that the proposed system can provide a larger system capacity and more effectively combat the partial band interference (PBI) than the conventional ones.
