Abstract

For Line-of-Sight (LOS) radio channels, recent research shows that in order to improve effectively the performance of a Multi-input Multi-output (MIMO) system, the antenna elements at the receiver must be separated on the scale of a symbol wavelength ([speed of light]/[symbol rate]). The main focus of this thesis was to design, implement and test a two-by-two (2X2) system based on that separation. The system was implemented on a single Field Programmable Gate Array (FPGA) board. The adaptive Space-Time (ST) receiver in the system includes a Least Mean Square (LMS) algorithm to adapt the coefficients. The system was developed using Altera Quartus II software and Verilog HDL was used as the coding language. The system was debugged and tested for convergence using MATLAB and the Altera SignalTap II Logic Analyzer software. The results indicate that the system converges successfully. The system's converged coefficients show selected ranges of zeros or small values.
