MIMO-OFDM系统中的无线资源分配算法研究
he Radio Resource Allocation Scheme in MIMO-OFDM Systems
MIMO与OFDM可以很好结合在一起，充分利用空间信道资源，减小多径干扰的影响，是下一代无线通信系统的首选技术。本文首先给出了MIMO-OFDM系统模型，并在此基础上分析总结了相关无线资源分配机制，以最大化系统吞吐量或最小化系统总功率为优化目标，自适应的进行子载波、空间子信道、比特功率分配。
MIMO combines with OFDM, which will utilize the spatial channel resource efficiency, reduce the multi-path interference, and will be the key technology for the next generational wireless systems. In this paper, the system structure of MIMO-OFDM is given. And based on this structure, the radio resource allocation schemes are summarized and analyzed. The optimization targets could be system throughput maximization or transmission power minimization, and the subcarrier, spatial subchannel, and power will be allocated adaptively.
