prophase

Upon the prophase work of our staff room, we have accomplished the system of QPSK modulation and demodulation on the whole. We want to implement wireless transmission of RS-232C asynchronous serial data through QPSK modulator and demodulator.

本教研室在前期的工作中基本完成了QPSK调制解调系统的研制和开发，在此基础上，想要实现RS-232C异步串行数据通过现有的QPSK调制器和解调器来进行无线传输。
