Web2、Rician衰落是在Rayleigh衰落条件下增加了视距信号,视距分量强度的大小用莱斯因子(K因子)来衡量。K因子定义为直射分量(常数)与Rayleigh随机变量的能量比。 k=\frac{P_{LoS}}{P_{Rayleigh}} 用基带等效模型来对Rayleigh衰落信道增。益和Rician衰落信道增益来进行建模。 WebThe Rician fading with parameter K = 0 (which the ratio between the LOS component and the reflexions powers) is the Rayleigh fading. Thus Rician can be used to model both (LOS and NLOS fading).

WebThe Ricean distribution is often described in terms of a parameter K which is defined as the ratio between the deterministic signal power and the variance of the multipath. K ( d B) = … WebThe derivation of the probability density function of amplitude is more involved than for Rayleigh fading, and a Bessel function occurs in the mathematical expression. It has been proposed to approximate this expression by the model for Nakagami fading, however, the behaviour of Nakagami and Rician fading in deep fades is essentially different.
WebFor Rician fading, the slope of the outage probability versus C/I is the same as for Rayleigh fading. For Nakagami fading, the slope is steeper, similar to that of m-branch diversity reception of a Rayleigh fading signal. Method for Link Evaluation. The nakagami approximation appeared less suitable to approximate a Rician channel. WebIf x has a Rician distribution with parameters s and σ, then (x / σ) 2 has a noncentral chi-square distribution with two degrees of freedom and noncentrality parameter (s / σ) 2. …

WebRician fading is a part of Rayleigh fading with the introduction of a strong line of sight path in the Rayleigh fading environment [7]. The received signal comprises of both the direct …
WebThe Rayleigh and Rician channel models are two widely used channel models in wireless communications. The Rician channel assumes that the transmission paths from the transmitter to receiver are comprised of the dominant LoS path and other scattering paths, whereas the Rayleigh channel consists of scattering channels from the transmitter to …
