—In this paper we focus on the analysis of the end-to-end outage probability of hybrid automatic repeat request (HARQ) in a multi-hop, block-fading channel. First, we use a Markov chain to model the multi-hop system with truncated HARQ type-I (HARQ-I) and derive closed-form expressions for the outage probability and throughput; we also obtain lower and(More)
We propose two high spectral efficient relaying protocols with low overhead including: the priority based relay selection (PRS), and the priority based relay selection with incremental transmission (PRSIT). In PRS and PRSIT, relay selection and scheduling are integrated to achieve full diversity order and high spectral efficiency. We define the overhead per(More)
