Performance Evaluation of Cooperative Relaying Technique in Mobile System

Abstract

Generally, Multiple Inputs Multiple Outputs (MIMO) is a promising technology for future wireless communications systems. By exploiting the multi-dimensional wireless channel created by multiple transmit and receive antennas, MIMO system significantly increase the channel capacity and link robustness of wireless communications. However, MIMO system is difficult to implement in mobile terminal due to the limitations of size and cost. The cooperative relaying system enables single antenna mobiles in a multi-user environment to share their antennas and generate a virtual multiple antenna transmitters. The relay helps the source to communicate with the destination to achieve reliable communication. This project investigates a single relay system that aims for a reliable communication. The main goal is to study the feasibility of the proposed single relay transmission system in the mobile environment and in addition proposed appropriate coding techniques to improve the reliability in terms of Bit Error Rate (BER).
