Recent advances in wireless
communication systems have increased the throughput over wireless channels and
networks. At the same time, the reliability of wireless communication has been
increased. As a result, customers use wireless systems more often.
In wireless communication, error free
transmission can be achieved by deploying multiple antennas whether at
transmitter or receiver side.4th generation of wireless can be
achieved by using MIMO in combination with OFDM. MIMO multiplexing (spatial
multiplexing) and diversity (space time coding) having OFDM modulation scheme
are the main areas of focus in our study. MIMO multiplexing increases a network
capacity by splitting a high signal rate into multiple lower rate streams. MIMO
allows higher throughput, diversity gain and interference reduction.
Data will be encoded using STBC.
Advantage of using STBC is that no feedback is being required to get the
channel information .Receiver complexity is also being reduced. Simplest of
those is Alamouti STBC. After that, Comparison will be made among different
space time block codes in order to find out the best one.
