Paper Abstract

Sphere-decoding (SD) algorithm is one of important detection scheme for the data detection of multiple-input multiple-output (MIMO) communication systems based on layered space–time structure, but it has a higher complexity in its pre-processing than the Maximum likelihood (ML) algorithm. For good performance and low complexity, an improved sphere-decoding algorithm for MIMO system is proposed by choosing effective search radius. It can reduce the complexity while having grid points in the sphere. The simulation results show that the proposed data detection algorithm for MIMO system has a very close to the traditional Sphere-decoding algorithm in Bit Error Rate (BER) performance, but it has lower complexity than traditional Sphere-decoding algorithm.
