Abstract

A hybrid automatic repeat request (HARQ) scheme based on a novel class of rate-compatible polar (RCP) codes is proposed. The RCP codes are constructed by performing punctures and repetitions on the conventional polar codes. Simulation results over binary-input additive white Gaussian noise channels show that, under a low-complexity successive cancellation decoder, the proposed HARQ scheme can perform as well as the existing schemes based on turbo codes and low-density parity-check codes. The proposed transmission scheme is only about 1.0 to 1.5dB away from the channel capacity with the information block length of 1024 bits.
