Recently, IEEE 802.11n system has proposed by demands for high throughput and this IEEE 802.11n system should build upon IEEE 802.11a system. This paper suggested simple way to implement 802.11a backward compatible transmitter diversity using multiple antennas in an 802.11a/802.11n device and simulated how much total throughput is enhanced in 802.11a MAC by using multiple antennas.
802.11n MIMO system should be built upon 802.11a SISO system. This paper suggests simple way to implement 802.11a backward compatible transmitter diversity using multiple antennas in an 802.11a/802.11n device. This paper also presents the method of antennas selection and shows the improved results of simulation. In transmitter, the channel state information (CSI) can be measured by using preamble...
