Hybrid automatic repeat request(HARQ) protocol using auto repeat request and front error control is always used for reliable high rate services for the purpose to improve the throughput and reliability of communication systems.According to analyzing the disadvantage of the traditional ARQ scheme,a new type HARQ scheme based on channel noise estimation is presented.The throughput and average transmission time are analyzed.Simulation results show that the proposed scheme achieves higher throughput,reduces the average transmission time and improves the reliability of the system.
