极化码编码的MIMO的图合并检测译码算法及装置
Abstract:
本发明公开了一种基于置信传播（belief proportion，BP）的多输入多输出（MIMO）检测和极化码（polar code）译码的图合并检测译码算法及装置，来进一步提高通信系统的稳定性，降低误码率。该方法通过将MIMO BP检测的因子图和极化码译码的因子图结合起来，使得他们之间的概率信息可以流通，进而使得对数似然比（Log likelihood ratio）可以具有更高精度而且可以更快的收敛速度。
Abstract(English):

The invention discloses a graph-merged detection and decoding algorithm of BP (Belief Proportion) based MIMO detection and polar code decoding and a device to further improve the stability of a communication system and reduce the error rate. As a factor graph of MIMO BP detection and a factor graph of polar code decoding are combined in the algorithm, the probability information between the factor graphs can be exchanged, and a more accurate log-likelihood ratio and a faster rate of convergence further can be obtained.
