摘要

在二进制CDMA (B-CDMA)方案中，将多个CDMA信号的包络量化为少量电平，在保留CDMA软容量和抗干扰性等优点的同时，最大限度地减少了放大器的功率负担。分析了B-CDMA系统在加性高斯白噪声信道(AWGN)下的性能。B-CDMA系统的性能主要受到两类噪声的限制。一种是截断噪声，由于信号被截断成有限电平，另一种是由于芯片误差引起的噪声。最后，通过计算机仿真验证了分析结果。

Performance analysis of binary-CDMA transceivers in AWGN channel

In binary CDMA (B-CDMA) schemes, the envelope of multiple CDMA signals is quantized into a small number of levels to minimize power amplifier burden while keeping the advantages of CDMA such as the soft capacity and robustness to interference. The performance of the B-CDMA system is analytically evaluated in the additive white Gaussian noise channel (AWGN). The performance of the B-CDMA system is mainly limited by two types of noise. One is truncation noise, due to truncation of the signal into a finite level and the other is the noise due to chip error. Finally, the analytical results are verified by computer simulation.
