Coding Error Exponents for Asymmetric Two-User
Discrete Memoryless Source-Channel Systems

Abstract
Consider transmitting two discrete memoryless correlated sources, consisting of a common and a pri-
vate source, over a discrete memoryless multi-terminal channel with two transmitters and two receivers.
At the transmitter side, the common source is observed by both encoders but the private source can
only be accessed by one encoder. At the receiver side, both decoders need to reconstruct the common
source, but only one decoder needs to reconstruct the private source. We hence refer to this system
by the asymmetric 2-user source-channel system. In this work, we derive a universally achievable joint
source-channel coding (JSCC) error exponent pair for the 2-user system by using a technique which
generalizes Csisz´ar's method [8] for the point-to-point (single-user) discrete memoryless source-channel
