Abstract

Measured channel impulse response estimates are used to predict the parameters of the channel model needed to evaluate the performance of RAKE receivers in microcellular CDMA systems. A channel model consisting of a number of resolvable multipath components is assumed. The parameters of interest are the relative average powers of the multipath components, the probability distribution of multipath fading on each path, and the cross-correlation coefficients of multipath fading among the different multipath components. This paper presents statistics on these parameters for measurements made in outdoor urban microcellular and indoor environments at 910 MHz
