Abstract:
In this paper, we have proposed the novel demodulation scheme of MFSK (M-ary Frequency Shift Keying) signals on MIMO frequency selective channel. For demodulating MIMO MFSK signals, we previously used the FDE (Frequency Domain Equalization) using CP (Cyclic Prefix). In order to further improve the BER characteristics, the novel scheme using MLD (Maximum Likelihood Detection) with ISI canceller and ZP (Zero Padding) has been considered. We further reduced the receiver complexity by replacing MLD with M algorithm. Through computer simulation, we have verified that the proposed scheme using M algorithm with ISI canceller exhibits the excellent BER characteristics compared with the FDE with CP.
