We consider strategies for the lossy transmission of a zero mean Gaussian source over a 2times2 MIMO channel with Rayleigh fading. The source is represented either using a single description or a multiple description code, depending on each strategy characteristic. Performance is evaluated using normalized expected distortion at the receiver, as a function of outage probability. The first strategy...
We consider strategies for the lossy transmission of a zero-mean memoryless Gaussian source over a 2times2 Rayleigh faded MIMO system with transmitter side information. The first strategy uses repetition coding, where the same symbol is duplicated over the two transmit antennas in two consecutive time slots. The second strategy employs the Alamouti scheme, while the third strategy is based on spatial...
Despite of performance improvement of multiple-input multiple-output (MIMO) system, the complexity and hardware cost is increased due to the using of multiple RF chains. Antenna subset selection is an alternative to mitigate the problem. Through selecting the best antenna subset, reduced number of RF chains can be deployed with small performance loss. In this paper, we propose a simple antenna selection...
Multiple-input multiple-output (MIMO) wireless systems use antenna arrays at both the transmitter and receiver to provide communication links with substantial diversity and capacity. Spatial multiplexing is a common space-time modulation technique for MIMO communication systems where independent information streams are sent over different transmit antennas. Unfortunately, spatial multiplexing is sensitive...
