Abstract :
This paper examines type-II ARQ (incremental redundancy) systems over equalized inter-symbol interference (ISI) channels. We study the error rate and throughput performance of hybrid ARQ using convolutional codes, turbo codes and serially concatenated single parity check (SCSPC) codes. SCSPC codes are shown to provide an excellent performance complexity trade-off. Results demonstrate that both convolutional and SCSPC codes can outperform turbo codes in the ARQ framework. This is in direct contrast to previous work on AWGN channels. Finally, we propose a design rule to find good packet lengths for systems based on SCSPC
