Belief-Propagation Decoding of LDPC Codes with Variable Node-Centric Dynamic Schedules
Tofar C. -Y. Chang, Pin-Han Wang, Jian-Jia Weng +2
Belief propagation (BP) decoding of low-density parity-check (LDPC) codes with various dynamic decoding schedules have been proposed to improve the efficiency of the conventional f…
An Information Bottleneck Problem with Rényi's Entropy
Jian-Jia Weng, Fady Alajaji, Tamás Linder
This paper considers an information bottleneck problem with the objective of obtaining a most informative representation of a hidden feature subject to a Rényi entropy complexity c…
Two-Way Source-Channel Coding
Jian-Jia Weng, Fady Alajaji, Tamás Linder
We propose an adaptive lossy joint source-channel coding (JSCC) scheme for sending correlated sources over two-terminal discrete-memoryless two-way channels (DM-TWCs). The main ide…
Adaptive Coding for Two-Way Lossy Source-Channel Communication
Jian-Jia Weng, Fady Alajaji, Tamás Linder
An adaptive joint source-channel coding (JSCC) scheme is presented for transmitting correlated sources over discrete-memoryless two-way channels subject to distortion constraints.…
Capacity of Generalized Discrete-Memoryless Push-to-Talk Two-Way Channels
Jian-Jia Weng, Fady Alajaji, Tamás Linder
In this report, we generalize Shannon's push-to-talk two-way channel (PTT-TWC) by allowing reliable full-duplex transmission as well as noisy reception in the half-duplex (PTT) mod…
Capacity of Two-Way Channels with Symmetry Properties
Jian-Jia Weng, Lin Song, Fady Alajaji +1
In this paper, we make use of channel symmetry properties to determine the capacity region of three types of two-way networks: (a) two-user memoryless two-way channels (TWCs), (b)…
Lossy Transmission of Correlated Sources over Two-Way Channels
Jian-Jia Weng, Fady Alajaji, Tamás Linder
Achievability and converse results for the lossy transmission of correlated sources over Shannon's two-way channels (TWCs) are presented. A joint source-channel coding theorem for…
Sufficient Conditions for the Tightness of Shannon's Capacity Bounds for Two-Way Channels
Jian-Jia Weng, Lin Song, Fady Alajaji +1
New sufficient conditions for determining in closed form the capacity region of point-to-point memoryless two-way channels (TWCs) are derived. The proposed conditions not only rela…
Optimized Signaling of Binary Correlated Sources over GMACs
Jian-Jia Weng, Fady Alajaji, Tamás Linder
This work focuses on the construction of optimized binary signaling schemes for two-sender uncoded transmission of correlated sources over non-orthogonal Gaussian multiple access c…
A Non-Disjoint Group Shuffled Decoding for LDPC Codes
Yen-Cheng Hsu, Tofar C. -Y. Chang, Yu T. Su +1
To reduce the implementation complexity of a belief propagation (BP) based low-density parity-check (LDPC) decoder, shuffled BP decoding schedules, which serialize the decoding pro…
