Precoding Method Interference Management for Quasi-EVD Channel

Algorithm 1

Cholesky decomposition-block diagonalization (CD-BD) algorithm.

(1)  Given the channel    and    for -pair

  users as in (2), may be decomposed as:

(2)  Fix the relay function    shown in (10).

(3)  Begin iteration.

(4)  Applying the MMSE channel inversion:

(5)  Compute the Cholesky factorization:

(6)  Compute the precoding matrix:

(7)  Compute the MSE matrix of the signal waveform estimation:

(8)  Compute the leakage interference:

(10) Stop iteration until convergence.
