1 引言随着扩频多址通信的发展,扩频正交码的研究愈来愈受到人们的重视。然而,现有的正交码序列的自相关或互相关的旁瓣较大,有的正交码序列自相关和互相关特性均不理想,这就给扩频系统的同步捕获带来困难,影响了通信多址利用率的提高,因此有必要寻找具有良
1 Introduction With the development of spread spectrum multiple access communication, spread spectrum orthogonal code more and more people’s attention. However, the existing orthogonal code sequences have a large sidelobe or high correlation coefficient and cross-correlation properties, which makes it difficult for the spread spectrum system to capture synchronously. Affecting the improvement of communication multiple access utilization, it is necessary to find good
