Abstract

We present an overview of an experimental 20 MHz 2×2 MIMO-OFDM system for operation at 3.65 GHz. The transmitted signal characteristics, data collection setup, measurement analysis, and timing acquisition algorithms are described. Field trials from a base station with two transmit antennas to a two-antenna mobile receiver are planned in a coverage area having a two mile radius. The first phase of the development process of this experimental system is complete, and initial laboratory results in the area of MIMO channel estimation and demodulation are presented for an indoor pedestrian MIMO channel
