On source and channel codes for multiple inputs and outputs: does multiple description beat space time? [PDF]
, 2005 We compare two strategies for lossy source description across a pair of unreliable channels. In the first strategy, we use a broadcast channel code to achieve a different rate for each possible channel realization, and then use a multiresolution source ...

Bilayer Protograph Codes for Half-Duplex Relay Channels [PDF]
, 2013 Despite encouraging advances in the design of relay codes, several important challenges remain. Many of the existing LDPC relay codes are tightly optimized for fixed channel conditions and not easily adapted without extensive re-optimization of the code.

An Achievable Rate Region for the Broadcast Channel with Feedback
, 2013 A single-letter achievable rate region is proposed for the two-receiver discrete memoryless broadcast channel with generalized feedback. The coding strategy involves block-Markov superposition coding, using Marton's coding scheme for the broadcast ...

Physical-layer Network Coding: A Random Coding Error Exponent Perspective
, 2017 In this work, we derive the random coding error exponent for the uplink phase of a two-way relay system where physical layer network coding (PNC) is employed. The error exponent is derived for the practical (yet sub-optimum) XOR channel decoding setting.

Near-capacity dirty-paper code design : a source-channel coding approach [PDF]
, 2009 This paper examines near-capacity dirty-paper code designs based on source-channel coding. We first point out that the performance loss in signal-to-noise ratio (SNR) in our code designs can be broken into the sum of the packing loss from channel coding ...

Polar Codes for Broadcast Channels [PDF]
IEEE Transactions on Information Theory, 2013 Polar codes are introduced for discrete memoryless broadcast channels. For $m$-user deterministic broadcast channels, polarization is applied to map uniformly random message bits from $m$ independent messages to one codeword while satisfying broadcast constraints.
