According to different channel models, CDMA systems can be divided into additivewhitegaussiannoise (AWGN) channel and dispersive channel, time-variant and time-invariant channel.
CD MA系统按信道模型的不同分为高斯白噪声信道和衰落信道、时变和时不变信道。

As some examples, the results of some TCM signal sequence on additiveGaussianwhitenoise (AWGN) channel and fading channels have been presented.
作为实例，给出了高斯信道和衰落信道上的一些TCM信号序列的自由空间距离的计算结果。

A presence detection algorithm based on the estimation of cyclic frequency for Phase Shift-Keying (PSK) signals in additivewhiteGaussiannoise (AWGN) is proposed in this paper.
