针对并行组合频谱通信的数据映射调制，提出了一种r组合方法。该算法应用了组合数学的理论和方法，实现了唯一的数据映射。本文讨论了并行组合频谱通信中应用的Gold序列、Walsh序列、m-W序列等PN序列，并给出了性能比较，并分析了PN序列的相关性、周期、数量的选择对PCSC系统性能的影响。
A r-combinatory method is proposed for the data map modulation of parallel combinatory spectrum communication.The arithmetic applies the theory and method of combinatory mathematics and achieves the only data map.PN sequences such as Gold sequence,Walsh sequence,and m-W sequence applied in the parallel combinatory spectrum communication are discussed and the performance comparison is given in this paper.The relativity,the period,the amount chosen for PN sequences that affect the performance of PCSC system are also analysed in this paper.
