WebWe will often assume an environment of a large number of scatterers so that the Rayleigh fading model is appropriate. The assumption of independent Rayleigh paths that we will also often make, is to be thought of as an idealized version of the result that for antenna elements placed on a rectangular lattice with half wavelength ( =2) spacing ...
