Abstract: It has been proved in literatures that the multilevel space time trellis codes (MLSTTC) provides higher order diversity with low complex component codes compared to single STTC. The throughput increases with manageable complexity compared to single space time trellis codes (STTC). But the computational complexity increases with the number of levels in the MLSTTC system. And also the metric calculation is a complex equation which needs more multiply and accumulate operation compared to single STTC. In this paper, reduced complexity decoding algorithm for multilevel space time trellis code is proposed to reduce the decoding delay and computational power required at the receiver. The simulation results show that the proposed algorithm gives a BER performance nearer to that of the system with full complexity. Further, the impact of correlation between the antennas in the system is also analysed. The simulation results show that with correlated antennas we could maximise the performance.
