基于比例公平的多用户MIMO-OFDM系统自适应资源分配算法
Adaptive resource allocation algorithm in multiuser MIMO-OFDM systems with proportional fairness requirement
摘要
Abstract
Conventional adaptive resource allocation algorithms in multiuser MIMO-OFDM systems have many problems, in cluding high computational complexity, time consuming, and they did not consider the proportional fairness among users. This paper presented a rapid adaptive sub-carrier, bit and power allocation algorithm. This algorithm ensured the proportional fair ness among users to minimize the transmit power while satisfying the rate requirement and BKR constraint of each user for sub carrier allocation. Furthermore, this algorithm could translate nonlinear optimization problems into linear optimization problems, and reduce the computational complexity effectively while ensuring the system performance. The simulation results show that this algorithm has good performance and can effectively reduce the computational complexity, and with proportional constraints the capacity is distributed more fairly and rationally among users.关键词
