- 초록
- For millimeter wave (mmWave) massive multiple-input-multiple-output (MIMO) Xhaul systems, an initial beam search technique based on the maximum value of the codebook multiplied by the channel correlation matrix is proposed. Simulation results show the proposed initial beam selection scheme reduces complexity by more than 95% and improves up to 24% gain in terms of achievable rate compared with the conventional turbo-like tabu beam search algorithm with a random initial beam selection.
