摘要:
混沌通信具有硬件实现低复杂度、低功耗和抗多径等特性,成为低速超宽带通信和无线传感网的候选方案.在各种混沌通信方案中,调频差分混沌键控因采用易于实现的非相干解调成为了研究的热点.本文提出一种新的增强型调频差分混沌键控通信系统,对每比特采样点数、每符号比特数和信号占空比对于系统性能的影响进行了分析,通过仿真证明了理论分析的正确性.
Abstract:
Due to the low com plex ity in hardwa re im plem entation, low pow er consum ption and robust in m ultipath env-i ronm ent of chao tic communication, chaotic communication is one o f the possib le candidate signa ls, app licab le to bo th low ra te U ltra W ide Band ( UWB ) sy stem s and w ire less senso r netwo rks. Am ong the m odu la tion schem es using the chao tic signa,l FrequencyM odulation Differential Chaos Sh ift Key ing ( FM-DCSK ) is a robust non- coherent techn ique w ith respect to the im plem enta tion issue and much research e ffort has been devo ted to the study of FM-DCSK. An enhanced FM-DCSK is proposed in the paper. The e ffects o f three sy stem charac ters such as the sam ples in one b it, the b its in one sym bo l and duty cyc le are ana lyzed, and the theory is proved by sim ulation.
