将一种新的扩频信号形式——序列偶引入到扩频通信系统中。依据扩频通信系统对扩频序列的技术要求,用遗传算法搜索出40至50长的次优二元序列偶,发现存在几个性能优于Gold序列的序列偶。提出了基于序列偶的扩频通信系统的构思,对这种扩频通信系统的性能进行了仿真,并同基于Gold码的扩频通信系统的性能进行了比较。实验结果表明,序列偶扩频通信系统的性能在某些方面优于Gold码扩频通信系统。
A new form of spread spectrum signal, a sequence pair, is introduced into the spread spectrum communication system. According to the spread spectrum communication system spread spectrum sequence requirements, using genetic algorithm to search for 40 to 50 long suboptimal binary sequence couple, found that there are several performance sequence Gold sequence better. The concept of spread spectrum communication system based on sequence pair is proposed. The performance of this spread spectrum communication system is simulated and the performance of spread spectrum communication system based on Gold code is compared. The experimental results show that the performance of the serial couple spread spectrum communication system is better than that of the Gold code spread spectrum communication system in some aspects.
