Abstract: In this paper, we analyze the impact of source correlation on the diversity and coding gains of a retransmission system where we aim to recover M erroneously received packets only by transmitting one helper packet utilizing the source correlation among the packets. This system is referred to as M-in-1 helper transmission. The helper packet is constructed simply by taking binary exclusive-OR of the M erroneously received information packets, notified via the feedback channel. To identify the trade-off between source correlation and performance gain due to coding and diversity, we start our investigation with in-depth analyses on rate regions and outage probabilities with M = {2,3}. We also evaluate the influence of unequal power and/or redundancy allocations between the helper and information packets. Finally, we provide the analytical results on achievable diversity order with arbitrary integer values of M. It is shown that M-in-1 helper transmission can always achieve M-th order diversity. Furthermore, (M+1)-th order diversity can be achieved with M being odd when the source correlation is very high; however, it cannot be achieved with M being even.
