| 摘 要： | 对短波环境下并行组合扩频系统进行研究,提出一种适合短波并行组合扩频通信的MPSK软解调方法。该调制方式比并行组合扩频常采用的MASK调制方式性能更好。在扩频增益相同条件下,短波并行组合扩频通信选取结构参数r值较小（r=2）的短波并行组合扩频系统为宜。在所选择系统结构的接收端应用RAKE接收技术,仿真表明RAKE接收技术能有效抵抗多径影响,改善短波并行组合扩频系统的误码率性能。

| Abstract: | This paper investigates parallel combinatorial spread spectrum（PC/SS） systems over HF channels.Propose a kind of soft demodulation method which is suit for HF communication.At the same condition of spread spectrum gain,the performance of PC/SS which structure parameter r=2 is better.RAKE receiver technonigy has been used in the receive of HF PC/SS.The simulation indicates that the BER is obviously improved by the adoption of RAKE receiver technonigy. |
