100, source UE stochastic generation source code coefficient matrix.
101, source UE utilizes source code coefficient matrix to be weighted process to sent data, obtains weighting matrix.
Wherein, data acquisition matrix form to be sent.
102, source UE carries out zero-adding to weighting matrix and amplifies process, is amplified matrix.
Weighting matrix is carried out zero-adding and amplify process, can think, for weighting matrix increases null matrix, to be amplified by the dimension of weighting matrix, to be amplified matrix.The null matrix of adding here is in order to observation and the interference of recording noise in transmitting procedure.Weighting matrix is the unique non-zero matrix in amplification matrix.
103, source UE adopts non-singular matrix to the weighting matrix in amplification matrix being carried out lifting process, obtains sending metrix.
Particularly, lifting process here, in order to protect weighting matrix, ensures that weighting matrix is intact, successfully can resolve the data getting this UE and will send at object UE.
