Algorithm 3
Optimized codebook algorithm.
step 1: Initialization | | Given | compute | step 2: For each set of a codebook where , compute the maximum value of PERs | over all MSs assigned to a set such that | | step 3: Eliminate a set over all existing sets such that | | step 4: For each MS in a set , compute over all existing beams except all beams in | a set . Then, assign MS to beam that maximizes such that | | step 5: Compute | step 6: If , | update | | | then go to step 2 | step 7: The algorithm terminates, then returns a set of MSs in , an optimized codebook | , and the expected number of transmissions . |
