低速率、大频偏PSK信号的调制解调是工程中一个较大的技术难题。本文阐述了一种用数字信号处理(DSP)技术解决此难题的方法,着重而详细地分析了调制解调器基带处理部分硬件电路的原理和功能的实现。在此基础上进一步探讨了功能扩展的可能性。
Modulation and demodulation of low-rate and large-frequency PSK signals is a major technical problem in the project. This article describes a method of using digital signal processing (DSP) technology to solve this problem, focusing on a detailed analysis of the modem baseband processing part of the hardware circuit principle and function realization. On this basis, further explore the possibility of function expansion.
