ABSTRACT
This chapter focuses on universal terrestrial radio access (UTRA) frequency division duplex (FDD) mode, because it is a more widely deployed system than UTRA time division duplex mode. Abstract Link capacity of cellular networks has become an issue with forecasted growing public demand for high data rate services. Multiple-input multiple-output (MIMO) antenna techniques have been received enthusiastically within wireless communications due to their potential to increase link capacities in a spectrally efficient manner. MIMO transceivers have great potential to improve the performance of wireless systems. Compared to wireline systems, the inferior capacity of wireless cellular systems is caused by several different physical constraints like co-channel and adjacent channel interference, channel propagation loss, and flat or multipath fading channels. Conventionally, multiantenna techniques have mainly been considered within base stations, because deploying multiple antennas in the user equipment is not straightforward due to cost, complexity of signal processing, and power consumption.
