Distributed Joint Source-Channel Coding for Relay Systems Exploiting Source-Relay Correlation and Source Memory
In this article, we propose a distributed joint source-channel coding (DJSCC) technique that well exploits source-relay correlation as well as source memory structure simultaneously for transmitting binary Markov sources in a one-way relay system. The relay only extracts and forwards the source message to the destination, which implies imperfect decoding at the relay. The probability of errors ...

متن کاملJoint source and relay optimization for parallel MIMO relay networks
In this article, we study the optimal structure of the source precoding matrix and the relay amplifying matrices for multiple-input multiple-output (MIMO) relay communication systems with parallel relay nodes. Two types of receivers are considered at the destination node: (1) The linear minimal mean-squared error (MMSE) receiver; (2) The nonlinear decision feedback equalizer based on the minima...
متن کاملMixed Joint Source-Channel Coding Schemes for the Multiple-Access Relay Channel: Error Probability Analysis
In the following we denote random variables with upper case letters, e.g. X , Y , and their realizations with lower case letters , e.g. x, y. A discrete random variable X takes values in a set X . We use pX(x) to denote the probability mass function (p.m.f.) of a discrete RV X on X ; for brevity we may omit the subscript X when it is the uppercase version of the sample symbol x. We denote vecto...
متن کاملJoint Source-Channel Cooperative Transmission over Relay-Broadcast Networks
Reliable transmission of a discrete memoryless source over a multiple-relay relay-broadcast network is considered. Motivated by sensor network applications, it is assumed that the relays and the destinations all have access to side information correlated with the underlying source signal. Joint source-channel cooperative transmission is studied in which the relays help the transmission of the s...
