摘要
本文介绍了一种基于低功耗单片机MSP430F1611和直接频率合成器AD9850的水声通信编码器的设计。系统可以产生稳定BPSK、2FSK、DSSS信号,并可以动态设置信号参数,界面友好,可灵活应用于各类水声通信实验。本文介绍了编码参数动态设置的硬件设计和软件实现,并对编码器的编码波形进行了测试。
A design of modulator based on low power-consuming MCU and DDS applied for underwater acoustic communications is presented in the paper. BPSK, 2FSK and DSSS waveforms can be obtained with flexible parameters setting. It can be widely used in application of all kinds of experiments of underwater acoustic communications. Hardware design and software debugging are discussed in the paper. Finally, the results of tests are listed.
