FPGA Spread Spectrum Communication Method Based on M Sequence

Abstract

As an important digital communication technology, spread spectrum communication has the characteristics of strong anti-interference and high spectrum utilization, and has been widely used in real life. At the same time, because FPGA has the advantages of data parallel processing capability and high flexibility, it is very suitable for researching and designing spread spectrum communication systems. Therefore, this paper designs a direct sequence spread spectrum communication method based on FPGA. By building the direct sequence spread spectrum communication system architecture and using modular design method, the behavior-level design of the direct sequence spread spectrum communication system has been realized, and it has passed the synthesis and simulation. It is verified that the system has strong anti-noise and anti-interference ability, and reflects the speed advantage of FPGA hardware in processing data.
