一种突发模式DSSS通信基带处理器及其FPGA实现

A DSSS Communication Baseband Processor in Burst Mode and Its Implementation Based on FPGA

针对一种无线突发模式ad-hoc通信系统,首先提出了DQPSK直接序列扩频(DSSS)调制解调器的设计方案,然后讨论了该基带处理器的同步、频差估计以及RAKE接收等关键技术,最后介绍基于FPGA的实现方法,实际应用证明了该方法的可行性。

In this paper, the design of DQPSK direct sequence spread spectrum modulator and demodulator aimed at a wireless high frequency burst mode ad-hoc communication system is presented first, and then some pivotal technology such as synchronization, offset estimation, RAKE receiver are discussed, finally the practical method based on FPGA is described, and practical application has proved its feasibility.
