Delay spread measurements on a wideband MIMO channel at 3.7 GHz

Abstract

This paper summarizes the delay spread characteristics of a 20 MHz MIMO channel at a carrier frequency of 3.676 GHz. The signals are transmitted from a two-antenna base to a two-antenna mobile receiver, and the experiments were conducted in a suburban setting outside Chicago, Illinois. The results include a statistical description of the delay spread environment. In addition, a case study of the temporal behavior of the channel is presented along with a one-bounce analysis to locate macro scatterers.
