Abstract :
In this paper, we study the performance of ARQ, HARQ I and HARQ II with code combining in the presence of feedback errors over multipath block fading channels. The performance of HARQ schemes in the presence of coded feedback is also investigated. In addition, it is shown that the derived analytical results are in excellent agreement with those obtained by computer simulations
