摘要
对现代潜艇扩频通信系统的相关接收情况进行分析 ,然后利用对多址干扰特征函数的积分求得直接序列扩频通信系统平均误码率的近似估计结果 ,并分析了用户信号功率。
In this thesis, a coherrent correlation receiver of spread-spectrum multiple-access communication system in a modern submarine is analyzed, and the corresponding characteristic function of the multiple-access interference is used to determined the average probability of error for direct-sequence spread-spectrum communication system, based on the integration of the characteristic function, then the efforts of signal power, the length of the signature sequences, and the number of interfering transmitters are illustrated.
