电力线通信系统中信道编码的FPGA实现

Implementation of the channel coding based on FPGA in power line communication systems

低压电力线通信是指利用现有的低压电力线网络进行语音及数据业务的一项新技术,而信道编码是不可或缺的重要组成部分。文章详细介绍了电力线通信系统中信道编码方案的FPGA实现,包括卷积码编码、交织、解交织, Viterbi译码的实现。并给出了实测的性能,讨论了FPGA具体实现的问题。

Low voltage power line communication that utilizes the existing low voltage power line network to transmit voice and data signal is a new technology, in which the channel coding is the indispensable important component. The article introduces the implementation of channel coding scheme based on FPGA in power line communication systems, including convolutional encoding, interleaving, deinterleaving, and Viterbi decoding. The performance of channel coding is tested, and the implementation how to use FPGA is discussed.
