【摘要】 BCH码是迄今为止所发现的一类很好的线形纠错码类。它的纠错能力很强,特别在短和中等码长下,其性能很接近于理论值,由于BCH码性能优良,结构简单,编译码设备也不太复杂,使得它在实际使用中受到工程技术人员的欢迎。本文根据BCH码的编译码原理介绍了一种BCH码——[15.7]码的编译码器的软件实现。该软件在VC++6.0的环境下编译完成,以文件的形式实现的,可以直接应用于PC机,因此在远程抄表,电力线通信等通讯方面都有应用参考价值。更多还原

【Abstract】 BCH codes are a very good kind of linear error correction codes that have been found by now.Their correction abilities are powerful.especially in the case of short and middle codes,their performance are very close to theory value.Because BCH code’s capability is powerful, their structure are simple and the devices of encoding and decoding are not very complicated, they are widely used in practice by engineering people.The text introduces a kind of BCH codes-[15,7] code’s software implement on the basis of encoding and decoding algorithm of BCH codes.The software is completed in VC++ 6.0 and is implemented in the form of files, which can be applied directly on computers.Therefore it has the reference values on long-distance transmission and power line communications and so on.更多还原
