摘　　要：扩频信号的跟踪解调既涉及到高速复杂数字逻辑的设计,又包括环路跟踪算法的设计。传统的设计中,一般采用FPGA+DSP的设计方式分别实现以上内容,与传统算法不同的是,基于FPGA的扩频信号跟踪解调电路采用片上可编程系统(SOPC)的设计思想,在FPGA中构建了处理器模块,从而使扩频信号的跟踪解调可以在一片FPGA中设计实现。Tracking demodulation of spread-spectrum signal involves not only the design of high speed complex digital logic but also the design of loop tracking algorithm.The traditional design,the general use of FPGA+DSP design methods to achieve the above content,respectively,and the traditional algorithm is different,based on FPGA spread spectrum signal tracking demodulation circuit using on-chip programmable system(SOPC)design ideas in the FPGA The processor module is constructed so that the tracking demodulation of the spread spectrum signal can be designed and implemented in an FPGA.
