| 中文摘要 | 该文提出实数域准零相关区序列的概念,当信道延迟和同步误差之和不超过零相关区长度时,可以较为理想地消除CDM A系统的码间干扰和多址干扰。同时,基于进化策略设计了实数域准零相关区序列的搜索算法,与传统零相关区序列的生成算法相比,该算法可以在全局解空间进行优化搜索,而且生成的序列在序列周期和零相关区长度等参数上较少受到构造方法的限制,更方便于实际应用。; A real number quasi-zero correlation zone(QZCZ) sequence is presented in this paper.The sequence exactly eliminates the inter-symbol interference (ISI) and multi-access interference(MAI) in CDMA systems with channel time delays and synchronization errors smaller than the length of the zero correlation zones(ZCZ).An algorithm is then presented to search for the real-number QZCZ sequence based on an evolutionary strategy(ES).Unlike traditional algorithms,this method searches for the optimal sequence in the general resolution space.The algorithm has less restriction among the sequences parameters due to the algorithm design,such as the sequence period and the ZCZ length,so it is more easily applied to practical applications.; 国家“九七三”重点基础研究发展计划资助项目(2007CB310600) |
