De-spreading Technique of One M-ary Orthogonal Spread Spectrum System
Kuang Jing-ming · Acta Simulata Systematica Sinica · 2003
Aiming at a kind of m-ary orthogonal spread spectrum mechanism, two kinds of receivers based on MSK modulation were given, one of which had the best theoretical performance and the other had practical utility. Both receivers, especially the second, were analyzed and then simulated by COSSAP to get the bit error rate(BER) in AWGN channel, and two approaches get similar results. Comparison between two receivers?simulating results also shows that with the same BER, the minimum signal power that the former can receive is lower by about 2dB than that of the latter.
