In some earlier work, MPC and PRPC are believed to offer higher throughput and better error correction capability at high bit error rate (BER) and large packet size only. An analysis was performed to substantiate this claim of higher throughput and better error correction capability in high as well as in low bit error rate (BER) for large and medium packet size. To conciliation high bit error rate...
Real-time video communication over wireless channels is subject to information loss since wireless links are error-prone and susceptible to noise. Popular wireless link-layer protocols, such as retransmission (ARQ) based 802.11 and hybrid ARQ methods provide some level of reliability while largely ignoring the latency issue which is critical for real-time applications. Therefore, they suffer from...
Previously, several modifications of the Weldon ARQ scheme for use in systems with limited receiver buffers have been studied. In the letter, an incremental redundancy ARQ scheme which uses rate compatible punctured convolutional codes is proposed and its throughput efficiency analysed. It is found that the system yields a comparatively high throughput over a wide range of channel conditions, thus...
