LPLC自适应速率传输技术的实现

THE REALIZATION OF LPLC RATE ADAPTIVE TRANSMISSION TECHNOLOGY

针对低压电力线信道复杂多变的特点,提出了根据信道环境实时改变数据传输速率的通信方式。其中,包括CRC检错码技术、ARQ重传技术、混合型ARQ自适应速率传输协议以及数据合并判决等方面的应用。最后,采用TMS320F2812DSP作为处理器,以FSK调制解调为通信方式,搭建电力线载波通信系统,实现自适应速率传输的低压电力线载波通信方案。

According to the characteristics of low voltage power line channel,this paper put forward the communication of changing data transfer rate according to the real-time channel. Including the CRC check words technology,ARQ retransmission technology,hybrid ARQ adaptive rate transmission protocol,and the data merging judgment,etc. Finally,unsing TMS320F2812 DSP as processor,FSK demodulation as communication mode,this paper set up power line carrier communication system,to implement LPLC adaptive rate transmission technology.
