| Abstract: | In the multi-input multi-output（MIMO） communication system, the complexity of sphere decoding algorithm is high when the signal-to-noise ratio is low and the modulation order is high. This paper proposes a new sphere decoding al- gorithm, which won＇ t affect the performance of the sphere decoding and reduces the complexity of sphere decoding. First- ly, we research the traditional sphere decoding algorithm. Then we present the imporved sphere decoding. According to the simulation, we verify the result. |
