Abstract:

Spatial multiplexing and spatial diversity are two efficient techniques to increase the data rate and to overcome fading respectively in LTE advanced system. They can be accomplished by employing cooperative MIMO, an advanced technology that exploits the spatial domain of fading channels in mobile communication. It uses distributed antennas on various relay stations to obtain reliability close to the MIMO. The underlying concept of this technology is to group multiple relays into an array of virtual antennas to form a MIMO. In this paper a new technique has been proposed for selecting the relay stations in forming a cooperative MIMO for transmission of message from base station to mobile station. The selection is done by comparing the error rate performance in relaying a pilot tone by the relay stations. The error rate in transmitting signal from both base station to relay station and relay station to mobile station have been considered while selecting the relay station for cooperation. Simulation results show that in the absence of one hop direct transmission of message signal from the base station to the relay station, proposed technique has reduced error rate compared to the error rate performance of the signal relayed by the selected individual relay stations. © 2017 IEEE.
