In this work, reliable and secure transmission over generic-Gaussian wiretap channel model is investigated. An Adaptive Granular Hybrid Automatic Repeat reQuest (AG-HARQ) protocol is proposed which tries to minimize the required rate for successful decoding by the legitimate parties while amplifying the privacy by minimizing the information leakage to a(More)
In communication systems, the transmitted data is corrupted by channel perturbations, such as noise and fading, which affect the reliability of the received data. Error correction codes are employed to mitigate channel perturbations. However, design and implementation of good and efficient error correction codes remains an open problem. In this paper, Low(More)
This paper proposes a physical layer coding scheme to provide reliability and security in wireless communication systems. An Adaptive Granular Hybrid Automatic Repeat re- Quest (AG-HARQ) scheme based on Low-Density-Parity-Check (LDPC) codes is proposed. In the AG-HARQ protocol, the whole codewords are first transmitted (by Alice) to the intended receiver(More)
