基于DSP电力线通信调制解调器的设计与实现

Design and Realization of Power Line Communication Modem Based on DSP

简要介绍了宽带电力线通信技术,选择OFDM作为宽带电力线通信中的调制技术。对OFDM的参数进行设计和芯片选择,介绍了TMS320VC5409的功能特点和结构,并以该处理器为核心,同时采用TLC876、AC101LKQT等外围芯片,开发了低压配电网的宽带电力线通信Modem。该Modem可应用于配电网。

The technology of broad band power line communication was introduced, OFDM as modulation technology in the broad band power line communication was chosen. The parameter of OFDM was designed and the digital signal processing chip was chosen, TMS320VC5409 function characteristic and the structure are introduced, taking this processor as the core and simultaneously using the periphery chip such as TLC876, AC101LKQT and so on, the broadband communication modem of low pressure distribution network was developed. The Modem can be applied in the power grid distribution.
