Abstract
This paper investigates the adaptivity of the Fixed Sphere Decoder (FSD) algorithm, for iterative-multiple-input multiple-output (MIMO) detection in 4G LTE environment. The switching mechanism for the FSD depends on the calculated mutual information between the transmitters and receivers in real-time. The detector determines whether the receiver would detect the incoming symbols using a higher accuracy detector, a less performance detector or simply abandon further processing and reduce energy consumption by requesting a re-transmission. This paper provides the performance analysis for the proposed algorithm in realistic conditions by providing a detailed energy analysis of the algorithm for spatially correlated channel conditions. Analytical, simulation and implementation results show that the practical behavior of the proposed lterative-MIMO detector saves significant energy with a tolerable bit error rate performance degradation.
