Multi-antenna systems have been shown to significantly improve channel capacity in wireless environments. The focus of this thesis is on the design of low-complexity multi-antenna receiver architectures for communication networks and their demonstration in a real-time wireless environment. Our practical realization of an orthogonal frequency-division multi-antenna receiver is capable of several forms of linear and iterative detection. Our implementation is based on a division-free reformulation of standard minimum mean-squared-error detection algorithms and uses complex dot-products as the basic building blocks of a folded-pipelined architecture. This folded-pipelined architecture provides significant area savings over non-folded approaches. The demonstration of our receiver architecture is carried out on a rapid-prototyping FPGA communication system. This prototype is used to validate our design and complement theoretical and simulated results with real-time laboratory measurements in a typical office environment.
