| Abstract: | 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. |
