Abstract :
Transmission reliability of data is an essential requirement of communication systems and multi-source Cooperation ensures it by allowing users to share their resources in order to collaborate through distributed transmission and processing of data. Another implication added on any communication system is that of a higher throughput, which is catered effectively by superposition coding. In this paper, a novel interleave division multiple access (IDMA) aided superposition coding scheme is considered. IDMA has been specifically designed for energy efficient multi-source cooperation. The concept of IDMA is introduced and the relation between superposition coding and IDMA is revealed. Our simulation results demonstrate improved signal to noise ratio (SNR) with reduction in bit error ratio (BER). Moreover performance comparison of single and multi-source communication is presented.
