利用中心Wishart矩阵的性质得到相关信道下的多输入/输出正交频分复用系统(Multiple Input Multiple out-put;Orthogonal Frequency Division Multiplexing,MIMO OFDM)的信道容量的上下界限,同时分析天线相关对信道容量的影响。假设接收端有完全的信道状态信息(CSI),而发射端没有任何的CSI的情况下得到了信道容量的上下界限,通过仿真说明得到的界限是紧凑的,同时说明信道相关如何降低信道容量。
摘要(英文):
In this paper, we derive the uppcr and lower bounds of the capacity of the MIMO- OFDM(Multiple Input Multiple Output;Orthogonal Frequency Division Multiplexing)system under cori'elated channels. We use the property of a central Wishart matrix to get the lower and upper bounds ergodic capacity formula. We assume that the transmitter has no Channel State information(CSI) and the receiver has perfect CSI. It is shown how the channel correlation degrades the capacity and our bo...
