Characterising mobile WiMAX performance

20 May, 2010 by Michael Lawton and Peter Cain

This article describes how a channel emulator can be used to characterise the performance of a MIMO receiver. The testing was done in stages of increasing complexity, namely, testing under AWGN conditions, MIMO testing with known static channels and, finally, testing with channels chosen to represent ‘real world’ behaviour.
