摘要
A method for performing a fast MSJM precoding 400 are provided. The method comprising: grouping input information bits into bit blocks (S410); Converting the bit blocks into bit vectors (S420); Comprising: mapping a first group of bits of each bit vector to the real dimension of symbols in the symbol vector (S430); A group of the second bit of each bit vector as a step (S430) that maps to the imaginary dimension of symbols in the symbol vector, which is the mapping of the real dimension and the mapping of imaginary dimension performed at the same time, the mapping step (S430); And a step (S440) modulating symbol vectors into data subcarriers. ;
