The goal of this thesis is to accomplish base - band channel coding / decoding , fh framing / de - framing and fh synchronization , and also to control the modulator and demodulator in the prototype system . all these functions are implemented with a tms320vc5409 dsp 作为项目的一个重要组成部分,本文采用dsptms320vc5409实现了基带处理部分的信道编解码、跳频意义的组拆帧和跳频同步、并对调制解调芯片读写寄存器进行了配置。
Phase modulation system is a superior system , can transmit data at high rate . in this thesis , digital fh - mpsk and fh - / 4dqpsk modulator and demodulator are given according to the frequency - hop communication characteristics . at last , we implement these systems in both hardware and software platform 本文根据跳频传输的特点,对mpsk和4 - dqpsk这两种相位调制方式进行分析,提出数字调制解调方案,并用matlab对其进行了仿真,最后还在ti公司的tms320c6416芯片上实现了这两种系统。
