| Abstract(in English) | We developed a maximum-likelihood detector (MLD) for multiple-input multiple-output (MIMO) systems, using a field programmable gate array (FPGA) device. For practical implementation, we introduce a simplified metric : referred to as a correlation metric. The correlation metric reduces the MLD complexity in multiplications from exponential order to cubic order according to the number of antennas, more remarkably without any performance degradation. The MLD prototype using the correlation metric has data processing capability over 1.3Gbps. In addition to the MLD prototype, we also implemented a 4×4 MIMO received signal generator on the same FPGA chip, for real time demonstration. |
