Algorithm 4 with the precoders W 1 and W 2. transmits codewords. | Step 1: Let c = 1. | Step 2: of , t ≠k, tries to decode and cancel codeword c of | (), using MMSE-SIC receiver. | Sub-step 1: If codeword c is decoded and cancelled successfully, for example, | , optimize the precoder at to maximize the rate of where | is given by (24) and replacing with the received interference plus noise | covariance matrix after cancellation of layers . Go to Step 3. | Sub-step 2: If codeword c could not be decoded correctly, for example, , | go to “end of Outer loop.” | Step 3: c = c + 1. If , go to Step 2. | End of Outer loop |
