     The article adopts the prevalent technique of DSSS to tackle the disturbance problem in the PLC. We design the peripheral circuit based on the modem chip SC1128 newly developed by ZYLH company in Beijing which suits for Chinese power grids, thereby we devise a PLC system and combine with the Error— Correcting Codes(ECC) in the software design of the MSPF149 MCU to further promote the reliability of the communication.
     本文采用当前流行的直接序列扩频技术(DSSS)来解决低压电力线载波通信中的干扰问题,根据北京智源利和公司最新研制的适合中国电力网的专用调制解调芯片SC1128,设计了相关的辅助外围电路,从而构造出低压电力线载波通信系统; 并在MSPF149单片机的软件设计部分结合了纠错码以进一步提高系统的通信可靠性。

In this paper, the developments and advances of error-correcting codes before and after year 1970 are described, putting emphasis on the latter. This paper consists of three parts: encode and decode of the block codes and the convolutional codes.

本文简略地回顾了纠错码七十年代以前的发展概况,着重谈了七十年代以后的发展情况及其趋势。全文共分三部分:分组码的编码、分组码的译码以及卷积码。

Byte error correcting codes are demanded in byte-oriented systems such as main memory, data transfer path, etc.. In this paper a class of single byte error correcting double byte error detecting codes (Sb/EC Db/ED codes) generated by means of the recursive process is presented. If the byte length is b, the length of checking part of the code is m bytes, the length of information part of the code is k bytes, then the maximal code length will be n=m+k=2m-2...

Byte error correcting codes are demanded in byte-oriented systems such as main memory, data transfer path, etc.. In this paper a class of single byte error correcting double byte error detecting codes (Sb/EC Db/ED codes) generated by means of the recursive process is presented. If the byte length is b, the length of checking part of the code is m bytes, the length of information part of the code is k bytes, then the maximal code length will be n=m+k=2m-2 (2b-1+1) bytes. In case of b= 1, these codes are the same with the ordinary binary Hamming SBC DED codes. Furthermore, another class of Sb/EC Db/BD rotation codes is produced with a computer. The length of such a code is longer than that of the previous one as the length of the checking part is increased.

对于面向字节组织的系统,如存储器、数据传输通路等,为了提高系统可靠性,需要采用能校正字节错的纠错码。本文提出一种用递归方法形成的单字节错校正双字节错检测码(S_bEC/D_bED码)。设字节长度为b位,该代码的校验部分长度为m字节,信息部分长度为k字节,则最大代码长度为n=2~(m-2)(2~(b-1)+1)字节。在b=1的特殊情况下,即为一般二元海明SEC/DED码。此外,用计算机推导出一种S_bEC/D_bED旋转码,这种码随校验部分长度的增加,具有比前一种码更大的代码长度。

The BCH code is a widely used error——correcting code. Although it can correct a number of errors if necessary, its efficency is not very high. The generalized BCH code improves the function of the BCH code. In this paper, the concept of the generalized BCH code is introduced, and its capacity of error——correcting is discussed.

BCH码是一类有广泛应用的纠错码,它可以根据需要纠正多个差错,但效率不是很高。广义BCH码改进了BCH码的性能。本文引进了广义BCH码的概念,并且探讨了它的纠错能力。
