摘要：

We present a novel method for decoding multiple-input multiple-output (MIMO) transmission, which combines sphere decoding (SD) and zero forcing (ZF) techniques. The proposed method provides a fixed complexity near optimal performance. This algorithm designed especially for systems with a large number of transmit antennas and allows efficient implementation in hardware. The high efficiency of this algorithm is obtained by limiting the number of overall SD iterations. Moreover, in the proposed method matrices with high condition number are more likely to undergo SD.
