A Game-Theoretic Precoding for Secure Communication in MIMO Interference Channels

Algorithm 1

Asynchronous Algorithm.

1. Initialization: set the iteration counter to , and start with an

arbitrary TPC matrix .

2. Begin the iteration: calculate and update and

according to the MMSE receivers in (8) and (9), respectively.

3. Update TPC matrix :

for    to    do

()

end

4. Repeat through 3 until is converged.
