摘要：
With iterative turbo decoding, the reliability of each bit in a frame is not same after some iterations. We propose novel bit-level hybrid automatic repeat request (HARQ) schemes with turbo codes in which only the unreliable bit and its neighboring bits are retransmitted based on the decoding reliability. The proposed bit-level HARQ schemes improve error performance compared with conventional HARQ schemes.
