The 4G wireless standards require MIMO systems with large antenna configurations, high mobility and, high data rates. In MIMO systems, the main challenge is to implement a QR decomposition process that efficiently utilizes hardware resources. By using MIMO technology in LTEAdvanced to achieves the highest detection throughput of 1Gbps data rates in downlink side. The proposed QR decomposition method is synthesized on Xilinx XC6VLX550T-2FF1759. Test results for the FPGA implementation, shows that the proposed design achieves the lowest latency of 100ns at 300MHz and reduces area. Keywords–FPGA, Hybrid QR decomposition, K-best detector, LTE-A, MIMO (Multiple Input Multiple Output).
