MIMO信道容量的研究


多输入多输出技术(MIMO)是种收发端均采用多天线的传输技术,相对单收发系统(SISO)而言,拥有更高的信道容量和其他优点,其信道容量很大程度上受天线的选择与数量影响。为此,本文主要对多天线传输的天线数量及选择对信道容量的影响进行了研究。
本文主要通过对典型系统的平均信道容量探讨以及仿真,将SISO,MISO,SIMO和MIMO等进行了相应的对比,对比了系统间的不同功率分配方法下和容量特征的信道容量,并且模拟仿真了最优天线选择算法以及次优天线选择算法下的系统平均信道容量。

关键词:多输入多输出,天线选择,功率算法,信道容量,降序天线选择。

Abstract

      Multiple input multiple output (MIMO) is a kind of multi-antenna transmission technology with multiple sending terminal and receiving terminal, in terms of relative single transceiver system (SISO), with higher channel capacity and other advantages, and the antenna selection and quantity affect the capacity of channel largely. Therefore, in this paper, the multiple antenna transmission antenna number and choice of influence on channel capacity is studied.
      In this paper, we mainly analyse the SISO, MISO, SIMO and MIMO and other several typical systems channel capacity on average, we compare the differences between the several system under different power scheme and algorithm (average power and water power algorithm) of the channel capacity, the optimal antenna selection algorithm and simulation and optimal antenna selection algorithm, the system average channel capacity.

Key  words : multiple input multiple output, Antenna selection, Power algorithm, Channel capacity, Descending antenna selection
