In wireless communication, user suffers from channel fading that is the signal attenuation varies significantly over the transmission. This can be overcome using proper diversity methods such as spatial, temporal, and frequency diversity. Cooperative communication introduces new diversity method called cooperative diversity. Cooperative diversity achieves with the cooperation of distributed relay nodes that help to establish a communication link between source node and destination node. Several theoretical studies have been carried out on cooperative communication and those studies suggest that the cooperative communication required less transmit power at the source and the relay. This makes cooperative communication is interference less and power efficient communication method. Also, cooperative communication enhances the coverage and the throughput of the system. A MIMO system uses multiple antennas at both the transmitter and receiver to improve the communication system performance by use of diversity and multiplexing techniques. MIMO system provides higher spectral efficiency, improves the reliability, fading mitigation and improved resistance to interference. Hence for the performance evaluation of the LTE system in downlink the proposed system determines the Bit Error Rate of the system for 2x2 MIMO channel applications. The System is developed here uses 2 input signal that needs to be transmitted over the channel.
