| Abstract(in English) | The paper describes a low complexity tree-structure based user scheduling algorithm in an up-link transmission of MLD-based multi-user multiple-input multiple-output (MIMO) wireless systems. An M -branch step by step selection algorithm, which selects M most-possible best branches at each step, is proposed to maximize the whole system sum-rate capacity. To achieve the maximized solution of the user scheduling algorithms in MIMO systems, antennas configuration and user selection are preformed simultaneously. According to the selected number of antennas of each user, different transmission schemes are also adopted by each user. Both the theoretical analysis and simulation results show that the proposed algorithms obtain near optimal performance with far low complexity comparing with the greedy search. |
