Antenna Selection Techniques in Single- and Multi-user Systems: A Cross-layer Approach (2006)
Abstract / truncated to 115 words
Over the last decade, the massive demand for high data-rate wireless applications has motivated the study and design of new communication technologies. Among all of them, multi-antenna schemes have been shown to provide remarkable benefits in terms of spectral efficiency. In order to achieve channel capacity bounds, some sort of pre-processing on the transmit side must be encompassed. Unless reciprocity between the forward and reverse links can be assumed, a feedback channel is required to convey channel state information. In such a context, transmit antenna selection emerges as an effective alternative requiring a low amount of information in the feedback channel. Antenna selection algorithms are usually designed in order to maximize physical layer performance but, ...
