A multipath channel model for mobile-radio communications

A model for the mobile radio channel is proposed that is intended to apply to wideband signals in the 900 MHz band. The model is specified by a two-variable impulse response h/sub x/(t), where x represents the location of the receiver. The model consists of two submodels, one describing the direct line-of-sight path, and the other the signal that reaches the receiver over simple reflections. This geometric model is spatially stationary but time-invariant. Time variation is the result of the receiver's motion that alters the point x. Moreover the model is based on physical reasoning and places no restriction on the transmitted signal.<
