摘要
基于能效分析了具有不同纠错能力的缩短BCH码在典型的无线传感器网络模型中的优劣。仿真结果表明,在典型应用中,缩短汉明码可以取得整体上最优的效果,并可通过对信息码长的调节取得最大能效,在对网络可靠性要求非常严格的情况下,可考虑使用纠错能力为2位或3位的缩短BCH码。
The performance of BCH coding with different error correction capacity in typical WSN is analyzed . Simulation shows that in typical application, shorten hamming code is optimal scheme on the whole, and the maximum energy efficiency can be got by adjusting the packet length in communication. In the case of application when the reliability is very, important, the shorten BCH coding which can correct 2 -3 bits error can be taken into account.
