... complexity and the extent of channel state information required at the receiver, we will introduce four types of combining schemes, including selection combining, switch combining, EGC, and MRC, in ... (Giannakis et al., 20 06) . In this section, we first present various receive diversity schemes, including selection combining, switch combining, equal-gain combining (EGC), and MRC. The well-known ... for handling inter-antenna interference, including zero-forcing (ZF), minimum mean square error (MMSE), interference cancellation, etc., are then introduced. The third part of this chapter introduces...
