A detection scheme of SCCPM system in slow frequency selective fading channel and simulation analysis of it's performance

In order to apply SCCPM system in slow frequency selective fading channel, a system design which interleaving many fading channel blocks is proposed. In the receiver end, we present a detection scheme which firstly apply frequency domain equalization algorithm on the oversampling SCCPM signal directly, and then apply iterative demodulation and decoding on the equalized SCCPM signal. The signal design and detection scheme have low complexity, and the detection complexity has nothing with multipath channel delay, it especially suitable for broadband system which multipath delay is great. Computer simulation results show that the signal design and detection scheme obtain a fading channel diversity gain and larger interleaving gain, so it has better performance. And through altering the number of interleaving blocks, a tradeoff of the performance gain and detection delay is achieved.
