KKTCode: Asymptotically Optimal Linear Codes for Noisy Feedback AWGN Channels
Hongjae Nam, Jonggyu Jang, Vishrant Tripathi +1
The design of optimal causal linear feedback schemes for additive white Gaussian noise (AWGN) channels with noisy output feedback has remained an open problem for over 60 years. Pr…
MaskCode: Mask Transformer for Feedback-Assisted Coding With Linear Block Codes
Jonggyu Jang, Hongjae Nam, Vishrant Tripathi +2
Feedback-based coding schemes have demonstrated substantial performance gains over today's open-loop coding schemes. Unfortunately, these gains are usually achieved in idealized se…
Analysis of Beam Misalignment Effect in Inter-Satellite FSO Links
Minje Kim, Hongjae Nam, Beomsoo Ko +4
Free-space optical (FSO) communication has emerged as a promising technology for inter-satellite links (ISLs) due to its high data rate, low power consumption, and reduced interfer…
Using Age of Information for Throughput Optimal Spectrum Sharing
Hongjae Nam, Vishrant Tripathi, David J. Love
We consider a spectrum sharing problem where two users attempt to communicate over N channels. The Primary User (PU) has prioritized transmissions and its occupancy on each channel…
Modeling and Analysis of Hybrid GEO-LEO Satellite Networks
Dong-Hyun Jung, Hongjae Nam, Junil Choi +1
As the number of low Earth orbit (LEO) satellites rapidly increases, the consideration of frequency sharing or cooperation between geosynchronous Earth orbit (GEO) and LEO satellit…
Modeling and Analysis of GEO Satellite Networks
Dong-Hyun Jung, Hongjae Nam, Junil Choi +1
The extensive coverage offered by satellites makes them effective in enhancing service continuity for users on dynamic airborne and maritime platforms, such as airplanes and ships.…
