Abstract
A Belief Propagation (BP) equalization method and apparatus, a communication device and a storage medium are disclosed. The method may include: splitting a received signal Y, a channel estimation Hand a symbol estimation Xinto real parts and imaginary parts to obtain a received signal matrix Y, a channel estimation matrix H and a symbol estimation matrix X (S); performing orthogonal triangular (QR) decomposition on the channel estimation matrix H to obtain an equivalent received signal Y, an equivalent channel R and a noise power σ(S); and performing iteration based on the equivalent received signal Y, the equivalent channel R and the noise power σto obtain a position probability of per stream symbol (S).
