Performance of efficient modulation communication system via multi-antennas

The efficient modulation communication systems via multiple antennas are considered. By using the impacting signals that been filtered after the special impacting filter (SIF) as the transmitted signals, the problem of combining the efficient modulation technique with the space-time coding has been addressed. Additionally, the theoretical analysis of the demodulation and the maximum likelihood (ML) decoding performance has been discussed. Numerical simulations support the theoretical analysing, show that the novel efficient modulation system via multiple antennas can achieve outstanding performance and enhance the space diversity compare with the single antenna efficient systems.
