Performance Guarantees of SIC-Based Decoding for VLSF Codes in Hardcore-Regulated MAC
Kevin Zagalo, Guodong Sun, Philippe Mary +2
Spatial regulation suffices to guarantee reliable, low-latency communication using variable-length stop-feedback (VLSF) codes over multiple access channels. The delay performance o…

Optimization of Sparse VLSF Codes for Short-Packet Transmission via Saddlepoint Methods
Guodong Sun, Samir M. Perlaza, Philippe Mary +1
In this work, we present an optimization framework for sparse variable-length stop-feedback (VLSF) codes based on a saddlepoint approximation, which jointly optimizes the decoding…
