ABSTRACT
Multimedia broadcasting has recently attracted a great deal of research interest [437, 438] along with growing wireless communication capabilities [439, 440] and the demand for audio and video streaming [2]. However, broadcasting systems traditionally suffer from heterogeneous channel conditions across receivers. A transmission scheme should normally ensure that all receivers can receive broadcasted information, resulting in the system performance often being constrained by the worst channel. This is likely to be exacerbated in future systems featuring multipleinput multiple-output (MIMO) technologies, which have increasingly become building blocks for high-capacity wireless link technologies such as 802.11n [439], WiMAX [440], and 3GPP LTE [441]. Devices in such networks may be equipped with varying numbers of antennas. We refer to this as receiver antenna heterogeneity.
