Ricean channel
Webbreceived signal strength and small-scale channel model represents the local average signal intensity prediction changes. Effect of mobility is that, channel varies with user’s location … WebbAs the K -factor is the ratio of the energy in the deterministic Line-of-Sight (LOS) component to the energy in the aggregation of the random scattered paths (i.e., the fading component), higher 𝐾 means that the channel is more deterministic.

Webbwhen the transmitter has knowledge of the statistics of the channel. The emphasis of this paper is on elucidating the novel mathematical methods used. We do this by analysing a … WebbA communication channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking. A channel is used for information transfer of, for example, a digital bit stream, from one or several senders to one or several …
WebbSELECTIVERICEANCHANNELS A. General Setups We consider a downlink scenario where the coverage of a high-mobility user is enhanced by a RIS. In this paper, a single antenna is used both at the BS and at the user, which minimizes the CSI estimation overhead in the high-mobility scenarios considered. WebbRayleigh and Rician fading channels are useful models of real-world phenomena in wireless communications. These phenomena include multipath scattering effects, time …
WebbThe answer by Prof. Emil Björnson is very quite, and I can add in other words that the Ricean fading channel can be modelled by the envelope of complex Gaussian process … WebbThe Rician K-factor is defined as the ratio of signal power in dominant component over the (local-mean) scattered power. In indoor channelswith an unobstructed line-of-sight …
WebbFit Rician Distribution with Known Scale Parameter Generate sample data of size 1000 from a Rician distribution with noncentrality parameter of 8 and scale parameter of 5. First create the Rician distribution. r = makedist ( 'Rician', 's' ,8, 'sigma' ,5); Now, generate sample data from the distribution you created above.
