Preserved Fulltext
We develop a general approach for joint source-channel matching based on a parametric distortion model that can be accurately applied to most classes of source and channel coders. ...
Application of joint source-channel matching in heterogeneous multi-media environments will demand general source-channel optimization schemes suitable for a wide variety of source coding standards, channel ...

In this letter, we propose a novel physicallayer network coding (PNC) scheme with log-likelihood ratio (LLR) conversion for fading channels, which utilizes not pre-equalizer at transmitters (source nodes ...
) but joint detector at receiver (relay node). ...
However, ideal channel estimation is required for pre-equalization and the preequalization with channel inversion is known to be quite power-inefficient in wireless communication links [13] . ...

These schemes select only the best relay from multiple relaying candidates to cooperate with a communication link. ...
We then propose a game-theory-based relay assignment scheme GTRA, in which each player plays against all the other players and determines whether to cooperate with a communication link on a packet-bypacket ...
In a wireless channel with higher variations, packets transmitted between a source and a destination are more likely to be corrupted. ...

In such networks, given a source and destination, it is of interest to compute a path and channel assignment on every link in the path such that the path bandwidth is the same as that of the link bandwidth ...
Such a path must satisfy the constraint that no two consecutive links on the path are assigned the same channel, referred to as "channel discontinuity constraint." ...
