摘　　要：为有效地提高测距精度和通信质量、解决测距模糊问题、易于保密处理,在实现数字化扩频通信技术时越来越多地使用长伪随机序列,这给接收机的捕获设计带来相当大的困难。为帮助解决长伪随机序列快速捕获问题,提出了一种快速计算长伪随机序列实时相位的算法,并给出算法的C语言实现。Long pseudo-random sequence has found wide application in spread spectrum communication technology for its remarkable advantages, such as improvement of ranging precision and communication quality, simple solution on fuzzy distance and easy secrecy. However these also brings some trouble in the implement of receivers, especially in capture design. A rapid arithmetic on real-time phase computation of long pseudo-random sequence is given in this paper, followed by its software implementation of C-Langnage code,in order to support the capture design.
