本文叙述了利用 MCS—48系列单片机8039实现的4800比特调制解调器的工作原理及设计方法。实验表明利用单片机实现的调制解调器不但可以满足各项技术要求,而且具有体积小、价格低廉、与计算机接口方便等特点。本设备完成了8DPSK 信号的调制(包括升余弦包络调制)及解调、提取定时信息、数字锁相等功能。
This article describes the use of MCS-48 Series 8039 microcontroller 4800-bit modem working principle and design method. Experiments show that the use of single-chip modem not only to meet the technical requirements, but also has the advantages of small size, low price, easy interface with the computer and so on. This device has completed 8DPSK signal modulation (including raised cosine envelope modulation) and demodulation, timing information extraction, digital lock phase and other functions.
