MIMO是满足高速无线系统日益增长需求的关键技术，它在发射机和接收机上使用多个天线。本文的目的是利用标准化组织(3GPP - 3GPP2)针对第三代移动通信系统提出的空间信道模型(SCM)来研究MIMO系统的容量。
从原理上说，MIMO系统的容量可以随着天线数目呈线性增加。本文首先总述了MIMO系统模型，然后评估MIMO系统在SCM传播场景（郊区宏小区和城市微小区）中的容量，并与i.i.d.和“One-Ring”信道模型的结果进行比较。仿真结果表明，更逼真的SCM信道容量并不随天线数量的增加而线性增长。
从实际应用的角度来看，小型MIMO系统是可取的。本文研究了互耦对密集天线单元的MIMO系统容量的影响。结果表明，对于较小的单元间距，互耦可能导致信道容量的增加或减少，这取决于所采用的信道归一化方法。
MIMO systems, which use multiple antennasat the transmitter and receiver, are a key technology to meet the growingdemand for high data rate wireless systems. The aim of this thesis is toinvestigate MIMO system capacity using the Spatial Channel Model (SCM),proposed by standardization bodies (3GPP-3GPP2) for third generation systems.In principle, the capacity MIMO systems can increase linearly with the numberof antennas. In this thesis, system model for investigating the MIMO system isfirst summarized. The capacity of MIMO systems in SCM propagation scenarios(suburban macro-cell and urban micro-cell) is then evaluated and compared withi.i.d. and ‘One-Ring’ channel model results. The simulation results show thatcapacity of the more realistic SCM channels does not increase linearly with thenumber of antennas. From the point of view of practical implementation, compactMIMO systems are desirable. In this thesis, the effect of mutual coupling onthe capacity of MIMO systems with closely spaced antenna elements isinvestigated. Results show that mutual coupling can lead to an increase ordecrease in capacity for small inter-element spacing, depending on the channelnormalization method employed.
