摘要:
如何提高信道编码的能力、降低误比特率,一直是信道编码研究的主要方向.为改善码字的误比特率性能,提出了一种不等能量分配方案,该方案根据基于一致界推导出的一个估计信息位误比特率分布的计算公式,对码字进行按位能量分配.并将该方法应用于不同类型的纠错码,通过和仿真结果比较显示,该方法可以很好地降低码字的平均误比特率,特别在高信噪比时,其效果更加显著.
Abstract:
How to improve the channel coding capacity and reduce the bit error rate has been the main re-search directions of channel coding. In order to improve the BER performance，based on a formula derivedfrom the union bound which can estimate the bit error rate for every position in the codeword sequence， a theo-retic method to optimize the bit energy is presented and applied to several kinds of channel codes. The analysisand simulation results show that the method can reduce the average BER noticeably，especially at higherSNRs.
