Partially-coherent distributed space-time codes with differential encoder and decoder
Abstract— Distributed space-time coding is a means of achieving diversity through cooperative communication in a wireless relay network. In this paper, we consider a transmission...

Network Coding over a Noisy Relay : a Belief Propagation Approach
Abstract— In recent years, network coding has been investigated as a method to obtain improvements in wireless networks. A typical assumption of previous work is that relay nodes...

A New Relaying Scheme for Cheap Wireless Relay Nodes
Wireless networks consist of senders, receivers, and intermediate nodes that collaborating (more or less) to establish the communication paths. Most of the researches in the domai...

Distributed Turbo Coding With Soft Information Relaying in Multihop Relay Networks
It has been shown that distributed turbo coding (DTC) can approach the capacity of a wireless relay network. In the existing DTC schemes, it is usually assumed that error-free deco...
