Generally speaking, a system employs multiple radio frequency antennas at both the transmitter and the receiver is referred to as a Multiple-Input Multiple-Output (MIMO) system. A typical MIMO system model is provided in Figure 1. Figure 1: The typical model for a MIMO system. As shown in Figure 1, the transmitter exploits transmit antennas, while the receiver exploits receive antennas. For example, the complex symbol transmitted by antenna 1 can be received by all the receive antennas, where the received complex symbols are , respectively. On the other hand, the received symbol at each receive antenna is actually the overlapped result of the symbols sent from all antennas. Furthermore, the wireless channel between the transmitter and the receiver is represented by a number of channel coefficients , each of which represents the specific channel link between a pair of transmitter and receiver. For instance, the channel coefficient is the link between the first transmitter and the first receiver, as plotted in Figure 1. In addition, the channel coefficients are often modeled as random variables conforming to specific distributions. The most widely used cha
