Multi-antenna schemes have been shown to provide remarkable gains in terms of spectral efficiency and extensive research has been dedicated to studying those in detail, discovering new setups in which multi-input multi-output (MIMO) schemes can be used and making them practical. This thesis is concerned with certain aspects of two particular setups in which MIMO techniques may be implemented, which we summarize below. - Limited feedback in the MIMO broadcast channel: We consider the downlink of a single cell where the base station (BS) has multiple antennas. A particular issue when dealing with such a system is that of channel state information at the transmitter (CSIT): this has been shown to play a cardinal role, particularly in the case ...
