Webvariation of GRAND designed for multipath flat Rayleigh fad-ing communication channels. Fading can significantly degrade the performance of wireless communication systems, hence diversity approaches are used to combat it.

GRAND for Rayleigh Fading Channels - arxiv.org

WebAbstract—Typically, a multipath channel response can be characterized as a sum of Rayleigh-fading ‘rays’, each defined by a time delay and a mean-square amplitude. Therefore, the channel response can be largely described by a power delay profile (PDP), which is the set of mean-square ray amplitudes and relative delays. WebThe purpose of this work is to present a study procedure and channel fading description, developed with MATLAB simulation. The channel is simulated as a FIR (Finite Impulse … The following variables control both the Rayleigh and Rician channel objects. By default, the channel is modeled as four fading paths, each representing a cluster of multipath components received at around the same delay. The maximum Doppler shift is computed as v*f/c, where v is the mobile speed, f is the … See more With the parameters specified above, we can now create the comm.RayleighChannel and comm.RicianChannelSystem objects.
