摘要
MSD算法给出了一种由符号检测错误概率决定的区间估计方法,并将得出的区间与SE准则下的检测区间相结合,寻求两者在调制信号星座图中的交集。仿真结果表明,该改进算法在保证解码性能的基础上,有效地降低了检测的复杂度。
Modified sphere decoder algorithm deduces a decoder district decided by symbol detection error rate, and elicits the intersection of the district and the other one deduced by SE criterion in QAM constellation. Simulation result has indicated that the modified algorithm has excellent performance as well as a lower complexity.
