Pilotless Frame Synchronization for LDPC-Coded Transmission Systems
Abstract--We present a pilotless frame synchronization approach that exploits feedback from a low-density parity-check (LDPC) code decoder. The synchronizer is based on syndrome ch...

Bit-Level Equalization and Soft Detection for Gray-Coded Multilevel Modulation
This paper investigates iterative soft-in soft-out (SISO) detection in coded multiple access channels, with Gray-coded M-ary quadrature amplitude modulation (QAM) for the channel ...

Error Resilient Non-Asymmetric Slepian-Wolf Coding
Abstract—We consider non-asymmetric distributed source coding (DSC) that achieves any point in the Slepian-Wolf (SW) region. We study the error propagation phenomena and propose ...

A Variational Inference Framework for Soft-In-Soft-Out Detection in Multiple Access Channels
We propose a unified framework for deriving and studying soft-in soft-out (SISO) detection in multiple-access channels using the concept of variational inference. The proposed fram...

A practical joint network-channel coding scheme for reliable communication in wireless networks
In this paper, we propose a practical scheme, called Non-Binary Joint Network-Channel Decoding (NB-JNCD) for reliable communication in wireless networks. It seamlessly couples cha...
