二隨機變量和-
According to the characteristics of uwb standard channel models, we propose the concept of “ composite lognormal random variables ( rvs ) ”. based on this new concept, a new and precise approach is proposed to approximate the statistical distribution of lognormal rvs ’ sum, which places no restriction on the distributional parameters and correlation between the two branches. then, we
在此基礎上,提出了一種新的對對數正態隨機變量和的統計特性進行近似的方法,該方法對變量的分佈參數和變量間的相關特性沒有任何限制,且精度較已有方法有了進一步的提高。
