Rateless Coding over Wireless Relay Networks Using Amplify/Decode and Forward Relays
In this paper two different rateless transmissionschemes are developed. In the proposed scheme, relay node candecode and forward the message to the destination if they areable to decode it, or amplify and forward the message to thedestination. Based on the analysis and simulation resultsprovided in this paper, the proposed method has bettertransmission time than the scheme which only the relay ...
متن کاملDistributed SNR-Based Power Allocation in Wireless Parallel Amplify-and-Forward Relay Transmissions Using Cournot Game
In wireless communications, power allocation plays a paramount role in sustainable network lifetime prolongation with quality-of-service and network interference reduction. This paper investigates a distributed power allocation problem in wireless parallel amplify-and-forward (AF) relay transmissions. Particularly, the objective is set to minimize the total transmit power while guaranteeing the...

متن کاملNetwork-coded retransmissions in wireless demodulate-and-forward relay channels
Consider the case where a source wishes to reliably deliver a number of data packets to the destination with the help of a demodulate-and-forward relay. We discuss two retransmission schemes, each of which can ensure that the packets from the source will be delivered to the destination without error. We first discuss a scheme that combines signals from the source and the relay at the destinatio...
متن کاملAmplify-and-Forward Relaying Based Multi-Relay Wireless Network Coding
This paper extends the amplify-and-forward based wireless network coding (AFNC) for single-relay network to multi-relay network with a chain topology. Direct application of the relaying protocol utilized in the conventional single-relay AFNC to the multi-relay scenario causes two major problems: the phenomenon of back stream of data, which we call data reflection, and inter-hop interference. We...
