摘要 跳时码的设计已成为超宽带无线电多址通信的研究热点。为了确保系统的可靠通信并减少多址干扰,跳时码必须具有良好的相关性能。研究了近完美序列相关性能,并提出基于近完美序列产生跳时码的算法。仿真结果表明该算法同比基于m序列的跳时码和随机跳时码的超宽带通信系统具有更低的系统误码率的性能。 TH （time-hopping）code design has become a hotspot in the research of ultra- wideband radio multi-access communication. In order to achieve reliable communication and decrease multi-access interference, good properties are required for TH code. The performance of almost perfect sequence is studied and the algorithm for generating TH code based on this sequence is proposed in the paper. Simulation results show that the proposed algorithm has lower BER than the TH code based on m series and random sequence in TH-UWB.
