Abstract

The enormous growth of wireless communication systems makes it important to evaluate the capacity of such channels. Multiple input multiple output (MIMO) wireless communication systems are shown to yield significant performance improvement to data rates when compared to the traditional single input single output (SISO) wireless systems. The benefits of multiple antenna elements at the transmitter and receiver have become necessary to the research and the development of the next generation of mobile communication systems. In this paper we propose the use of relaying MIMO wireless communication systems for use over long throughput. We investigate how relays can be used in a "demodulate-and-forward" operation when the transmitter is equipped with spatially correlated multiple antenna elements and the receiver has only partial knowledge of the statistics of the channel. We show that relays between the source and destination nodes of a wireless communication system in MIMO configuration improve the throughput of the system when compared to the typical MIMO systems, or achieve the desired channel capacity with significantly lower power resources needed.
