Abstract
In the following paper, we present asymmetric turbo hybrid automatic-repeat-request (ATH-ARQ) schemes that employ component code selection and asymmetric rate compatible punctured turbo codes (ARCPT) for enhanced performance in fading channels. The paper also presents a novel low-rate ARCPT encoder structure. An analysis is presented for efficient ARCFF puncture schemes for improved throughput performance at low and high SNR values. It is shown that in certain instances, the use of conventional turbo code structures results in the best performance
