Abstract

In this paper, we introduce a new constellation scheme to have better performance (in terms of BER) with respect to the conventional rectangular QAM constellation. We compared the new one and two new kinds of circular constellations with QAM. They were chosen so that they have the same average power. Also we compared the effects of using FHT and FFT for all constellations. Based on the results, the new constellations to provide slightly better performance in channels which have maximum SNR=20 dB. Also it is shown that the new constellation has better performance for the noisy channels (AWGN and burst) with ISI and low SNR. Also we have shown the effect of channel length with respect to cyclic prefix in this system.
