【摘要】 在假定多用户干扰等效于高斯分布的条件下，讨论了网格编码调制（ＴＣＭ）在ＡＷＧＮ信道下的性能．通过和非编码扩频多址（ＳＳＭＡ）下的性能比较，得出了ＴＣＭ－ＳＳＭＡ系统在一定信噪比条件下，性能比ＳＳＭＡ系统要好的结论．更多还原

【Abstract】 The performance of TCM in the AWGN channel is discussed, with the assumption of multi user interference being a Gaussian distribution. It is shown that compared with the uncoded SSMA system, the performance of the TCM SSMA system is better under a given S/N ratio.更多还原
