The demand of different multimedia services and different internet
supported applications on mobile devices requires a high speed data rate
and good service of quality. This can be obtained by implementing
multiple Antenna technology on both stations i.e. User terminal and base
station with an appropriate coding technique, and on the other hand MIMO
can fulfill 3G & 4G demand and standard with a combination of other
techniques. The system's error performance is analyzed through
simulation which showed the simulated results of Multi-Rate Resource
Control (MRRC) scheme and Alamouti scheme are identical. And also the
Bit Error Rate (BER) were checked for different MIMO systems. By
improving the BER, we will get the better QoS.
