| 摘 要： | 针对多天线正交频分复用(Multi In Multi Out-Orthogonal Frequency Division Multiplexing,MIMO-OFDM)系统,基于非实时业务对传输速率有最低要求的条件,考虑系统吞吐量最大化的子载波分配优化模型。在利用匈牙利算法进行求解后,对部分分配进行调整,可以使得尽可能多的用户最小传输速率得到满足。仿真结果表明,与历史文献中的结论相比,调整后的模型在使更多用户能满足最小传输速率要求的同时,还能提高系统吞吐量,并且满足公平性准则。

| Abstract: | Considering that the non real-time service always require a minimal transmit rate,an optimized subcarrier allocation model which maximizes the system throughput and subjects to the minimal rate for each user is studied based on MIMO-OFDM(Multi In Multi Out-Orthogonal Frequency Division Multiplexing) system.Firstly,the Hungarian algorithm is used to get the subcarrier allocation scheme,and then,some adjustments to the scheme is introduced to make sure that the allocation satisfies the requirement of the mini... |
