In this paper, we consider network coded (NCed)Hybrid-ARQ (HARQ) for multiple unicast ﬂows. The main contribution of the paper is the derivation of throughput expressionfor NCed HARQ with arbitrary number of users in i.i.d. channels.We apply the result to Rayleigh fading channels for incrementalredundancy (IR) and chase combining (CC) based NCed HARQ.We verify the analytical approach with simulations. We observesubstantial SNR improvements over regular ARQ with networkcoding as well as classical (H)ARQ. The SNR gains in the highand low throughput regimes are mainly due to the networkcoding and HARQ aspects, respectively. For low SNRs, NCedHARQ with IR surpasses the CC performance.
