Wesley A. Miller, "Parallel MIMO multiuser RF channel measurements and analysis with focus on impulse response and MMSE gain variations with antenna placement," Master's thesis, Dept. of Electrical and Computer Engineering, University of New Brunswick, (Fredericton, NB, Canada), Apr. 2010.


A multiple channel antenna testbed is constructed and configured for analysis of channel impulse responses. Transmit signals are generated using an Altera® Stratix® II field programmable gate array (FPGA) and hardware-modulated onto the radio frequency (RF) carrier. Received RF signals are down-converted to an intermediate frequency carrier using a commercial RF front end, sampled at FPGA analog-to-digital converters, and software-demodulated offline using MATLAB®. Matched sliding correlators are applied to the received signals to yield the channel impulse responses, which are then placed into a least-mean squares (LMS) adaptive filter simulation to evaluate minimum mean squared error (MMSE) performance for several indoor and outdoor antenna layouts in the 1900 (MHz) Personal Communications Services C2 band as per Standard Radio System Plan 510. MMSE values from simulation show improvement for the indoor far-spacing case over the indoor close-spacing case and the outdoor cases.
