Abstract:

This dissertation investigates several main challenges to implementing hardwarebased wireless fading channel emulators with emphasis on incorporating accurate correlation properties. Multiple-input multiple-output MIMO fading channels are usually triply-selective with three types of correlation temporal correlation, inter-tap correlation, and spatial correlation. The proposed emulators implement the triplyselective fading Channel Impulse Response CIR by incorporating the three types of correlation into multiple uncorrelated frequency-flat Rayleigh fading waveforms while meeting real-time requirements for high data-rate, large-sized MIMO, andor long CIR channels. Specifically, mixed parallel-serial computational structures are implemented for Kronecker products of the correlation matrices, which makes the best tradeoff between computational speed and hardware usage. Five practical fading channel examples are implemented for RF or underwater acoustic MIMO applications. The performance of the hardware emulators are verified with an Altera
