中文摘要：
提出了一种在边际自适应（MA）准则下，子载波分配、自适应调制、比特加载、成型滤波联合优化的设计算法，且通过对反馈信道的瑞利衰落模型假设，引入反馈系数的概念以对抗反馈信道误差造成的性能损失,仿真结果表明，提出的联合优化的自适应资源分配方案较之固定分配方案提升性能3dB，并能减轻反馈信道误差带来的性能损失2～3dB．
英文摘要：
A transmission scheme as a concatenation of dynamic sub-carrlers and bit assignment, selfadaptive modulation and beam-forming was proposed. By use of Rayleigh fading model assumption, a new concept--the channel feedback coefficient was introduced, so as to compensate the error inducted by feedback channel. Simulation results show that the proposed resource allocation scheme outperforms the multi-user MIMO-OFDM with static allocation technique by 3 dB, and could lessen the performance loss from channel state information feedback error by 2～3 dB.
