摘要
研制带宽效率高（η≥３ｂ／Ｓ／Ｈｚ）的数字通信系统，需要高元（Ｍ≥８）调制技术．本文介绍了一种用单片机实现的程控式８ＰＳＫ（调制）解调器。其特点是设备简单、性能可靠、经济，具有较好的实用价值和应用前景。
High-cell(M≥8) modulating technology is needed in the development of high efficiency bandwidth (η≥3b/s/Hz) dagital communications system. This paper describes the program-controlled modem of 8PSK with the help of monolithic computer. With features like simplicity of equipment, relibility of properties and economy, this modem claims good practical values and wide application prospects.
