A Novel Hybrid ARQ Scheme Based on Shift Column Permutation Bit Interleaving for OFDM Systems

In this paper, a novel hybrid ARQ scheme based on shift column permutation bit interleaving is proposed for OFDM systems. When a packet is requested for retransmission, we can use bit interleaving based on a shift column permutation to maximize channel diversity gain, which increases the system performance. The proposed scheme improves the performance of… CONTINUE READING
