Abstract: This paper presents new recommendations for the discrete sampling of a mobile radio with non-line-of-sight Rayleigh fading and a Jakes power spectrum. The results are derived from a new analytical result for the variance of the local-mean voltage using discrete, spatial sampling with uniform spacing. The variance presented here accounts for the correlation between the samples and significantly changes the number of samples that are required to estimate the local mean voltage with a 1 dB spreading factor.
