  • 基于单矢量传感器对码分多址水声通信进行了研究. 利用单个矢量传感器自身指向性进行方位估计最为常用的方法是平均声强器和复声强器, 但这些方法对于同频带的多用户来说, 理论极限仅能测量两个用户. 提出了有源平均声强器, 利用扩频通信中伪随机码优良的自相关和互相关特性, 可同时测得多个用户的方位, 利用估计的用户方位构建矢量组合, 调整矢量传感器的指向性, 实现各用户定向通信, 抑制多址干扰, 增加处理增益, 降低误码率. 对频带相同的扩频多用户通信进行了仿真及试验研究, 验证了有源平均声强器的有效性和实用性.
    Code divided multiple access (CDMA) underwater communication based on single vector sensor is studied in this paper. The most common methods to estimate azimuth with self-directivity of single vector sensor are average sound intensity method and complex sound intensity method, however, for the same frequency band multi-users, these methods are limited to the measurement of azimuths only for two users at the same time theoretically. An active average intensity method, which measures the azimuths of multi-users simultaneously with the excellent correlative characteristics of pseudo-random code in spread spectrum communication, is proposed in this paper. With the estimated azimuth, vector combination can be generated to adjust the directivity of vector sensor, achieve multi-user beam communication, inhibit multi-path interference, and enhance processing gain and lower error rate. Simulation and experiment for same frequency band spread spectrum multi-user communication testify the feasibility and utility of active average sound intensity method.
