宽带电力线载波系统中的信道编码技术研究
电力线载波通信具有网络覆盖范围广、接入方便的特点,但电力线不是一种理想的传输信道,其信道传输环境恶劣,不但具有阻抗匹配和频率选择性衰减的问题,而且还存在着严重的噪声和干扰。长期的实践证明:对抗恶劣电力线信道的最有效手段是信道编码技术,HomepulgAV标准中给出了双二元Turbo编码构造以及码内交织方案,但这种编码已经被国外通信设备商申请了专利,如果照搬恐会引起知识产权纠纷,因而给出了一种新的Turbo码交织方案,其性能比HomeplugAV标准略有提升,复杂程度完全相同,并给出仿真结果。...

Long time practice proved that the best way to overcome the problem of PLC channel is channel coding. In HomeplugAV standard give out a double binary Turbo coding structures, but for commercial reason, this Turbo interleave structure has become the patent product of oversea telecommunication equipment manufacturer, if use this T |
