摘　　要：馈线自动化对通信系统的要求是造价低、抗干扰能力强,可靠性高、实时性强。为此在馈线自动化系统中选择有线(双绞线)通信方式,采用OFDM技术实现数据传送,并用数字信号处理器(DSP)实现数据的调制与解调。设计了基于DSP实现OFDM信号的调制解调器,满足了通信系统的要求。Feeder automation requires that the communication system has the characteristic of low cost, strong anti-interference, high reliability and much more real-time ability. Therefore, wire （twister-pair） communication manner is chosen in the feeder automation system. The proposed system uses OFDM technology to transfer data, and adopts DSP to modulate and demodulate the data. OFDM signal modem is designed based on the DSP, which can meet the need of the communication system.
