考虑一个相干解调的同步直接序列扩频多址通信系统，给出了采用预去相关发射机基站的发射功率统计特性。结果表明，一个Ｋ用户基站的总发射功率的最大值与特征波形互相关系数平方成反比，发射功率的标准差为Ｏ（Ｋ－１）。当特征波形互相关系数小于２０％时，和传统系统相比一个基站的总发射功率不会大于１．９４ｄＢ
Considering a coherent demodulated synchronous direct sequence spread spectrum multiple access communication system, the statistical properties of transmit power using pre-decorrelated transmitter base stations are given. The results show that the maximum total transmit power of a K-user base station is inversely proportional to the square of the cross-correlation coefficient of the characteristic waveform, and the standard deviation of the transmit power is O (K-1). When the correlation coefficients of the characteristic waveforms are less than 20%, the total transmit power of a base station will not be larger than 1.94dB
