摘要
介绍了一种基于r-组合的并行组合扩频通信的数据映射算法,该算法应用组合数学中的理论和方法,实现了映射的唯一性,在该算法下讨论了应用于并行组合通信的Gold序列、Walsh序列、m-W序列,给出其性能比较,分析了码相关性、码周期、正交码个数及发送码个数等因素对并行组合扩频通信系统性能的影响。
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.
