摘要: |
提出了一种改进的V-BLAST译码算法。接收机首先根据特定的准则在整个信号空间中进行搜索并得到一个子集,然后根据最大似然准则从该子集中选取合适的信号矢量作为译码结果。该算法可以取得和最大似然译码算法相近的译码性能,并且具有很低的计算复杂度。 |

An Improved V-BLAST Decoding Algorithm |

Abstract: |
An improved V-BLAST decoding algorithm is proposed.According to a certain criteria,the receiver searches through the full signal space and obtains a subset.The final decision is made by selecting the proper signal vector from the subset with the maximum-likelihood(ML) principle.This decoding algorithm can achieve near-ML performance at low complexity. |
