Abstract
Applying an antenna array at a link end of a mobile communications system enables the realization of two types of gain: diversity gain on one hand, array gain (also called beamforming gain) on the other. These two types of gains are fundamentally different in nature. What is the relation between them, am-plifying or contradicting? Is there an optimum trade-off between them? How can they be exploited by signal processing? Does every spatial radio channel offer these gains? Is there a difference between transmitting and receiving with an antenna array? These and some more questions will be answered in this chapter.
