A maximum likelihood detector (MLD) is presented for 4x4 QPSK Multiple-input multiple-output (MIMO) systems. A hybrid methodology combining precomputation of norm values followed with the transformation of the maximum likelihood algorithm is applied in order to achieve an efficient MLD implementation, in which 16 norm values are concurrently computed for high throughput while maintaining power and area efficiency. The MLD implementation results are compared with a conventional MLD in area and power. Simulation results demonstrate that the proposed MLD can achieve up to 74 Mbps throughput at a clock speed of 14 7MHz.
