Abstract
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
