Minimizing The Expected Distortion Using Multi-layer Coding Approach In Two-Hop Networks
This work concerns minimizing the achievable distortion of a Gaussian source over a two-hop block fading channel under mean square-error criterion. It is assumed that there is not a direct link between transmission ends and the communication is carried out through the use of a relay, employing the Decode and Forward (DF) strategy. Moreover, for both of transmitter-to-relay and relay-to-destinat...
متن کاملThe Expected Achievable Distortion of Two-User Decentralized Interference Channels
This paper concerns the transmission of two independent Gaussian sources over a two-user decentralized interference channel, assuming that the transmitters are unaware of the instantaneous CSIs. The availability of the channel state information at receivers (CSIR) is considered in two scenarios of perfect and imperfect CSIR. In the imperfect CSIR case, we consider a more practical assumption of...
متن کاملSuperposition Coding for Costa Channels
We present practical codes designed for the Gaussian dirty paper (Costa) channel. We show that the dirty paper decoding problem can be transformed into an equivalent multiple-access problem, for which we apply superposition coding. Our approach is a generalization of the nested lattices approach of Zamir, Shamai and Erez. We present simulation results which confirm the effectiveness of our meth...
متن کاملOptimal source coding and transmission power management using a min-max expected distortion approach
We consider the problem of compressing a video sequence for transmission over a wireless channel. In our approach we jointly consider error resilience and concealment techniques, at the source coding level, and transmission power management at the physical layer. We formulate a minimum -maximum distortion problem, where our goal is to either (i) minimize the total transmission energy for a give...
متن کاملSuperposition network coded cooperation for wireless networks
Cooperative diversity is an innovative approach to improve the reliability of communication. Although this technique is considered in the next-generation mobile communication standards, it has its own challenges in practice. For example, in simultaneous transmission-based cooperative protocols, perfect synchronisation of nodes is very hard to realise. The traditional time division multiple acce...
