Abstract
Multiple antennas at the transmitter and receiver increase the capacity in a wireless communication system. Received signal quality can be enhanced through diversity by transmitting the same symbol on multiple antennas. Data rate can be increased through multiplexing by transmitting different symbols on the transmitting antennas. Operating in one particular mode only is generally not suitable. Choosing diversity or multiplexing by taking into account the location of a user can enhance both throughput and reliability.
