Hi,
In Matlab we can define Rayleigh fading as:

(randn(1)+j*randn(1) )/sqrt(2).

How can we define the Rician fading channle with K?

Re: Rician fading?

Hi,
Rician fading happens when there is a specular component in the received signal. You can simply change the mean of either real or imaginary or both of the complex Gaussain RV to get the Rician fading.
one method is :
(k*cos(t) + randn(1)/sqrt(2))+j*[k*sin(t) + randn(1) )/sqrt(2)], where t is any real number and K is the Rician factor. You can change the second moment of Rician distribution also in the same way by multiplyng the Gaussian Random variables with the square root of the required second moment.
Hope that helps,
vish
