Finally, numerical results of BER are analysed and implementation of error correcting coding is presented to improve the reliability of the AJES system. 最后,对误比特率的数值结果进行了分析,并提出了采用纠错编码的方法来改善AJES系统的可靠性。
Numerical results demonstrate the correlation among the transmission path decreases the coding gain of the system 1~ 2 dB. 对所得理论结果进行数值仿真,结果表明相关性使系统编码增益降低1~2dB。
