24112 该方法首先在 IEEE802.15.4a 信道模型下对均方根时延扩展和平均超量延迟的概率分布函数进行建模,作为信道标准分布。 The probability distribution function of Root Mean Square Delay Spread (RMS) and Mean Excess Delay (MED) under IEEE802.15.4a standard is modeled as standard distribution.
24113 再以信道瞬时分布与标准分布间的 KL 散度为检验统计量做似然比检验(Likelihood Ratio Test, LRT)来鉴别信道状态。 Channel state is identified by Likelihood Ratio Test (LRT) based on KL divergence between channel instantaneous distribution and standard distribution.
