Abstract :
Decompositions of fading dispersive channels find utility in channel modeling and in the estimation of channel state information in a receiver. This letter considers decompositions based on the f-power series and Karhunen-Loeve expansions and investigates their relative ability to model selected channels. Development of such models should enable the design of reduced complexity receiver structures
