Vectorized Generalized Nearest Neighbor Decoding for In-block Memory Channel
Yuhao Liu, Xinwei Li, Shuqin Pang +2
This work extends the generalized nearest neighbor decoding (GNND), originally developed as a receiver architecture for memoryless channels, to a vectorized GNND (Vec-GNND) suitabl…
An Optimal Transport-Based Method for Computing LM Rate and Its Convergence Analysis
Shitong Wu, Wenhao Ye, Xinwei Li +4
The mismatch capacity characterizes the highest information rate of the channel under a prescribed decoding metric and serves as a critical performance indicator in numerous practi…
Alternating Maximization Algorithm for Mismatch Capacity with Oblivious Relaying
Xinwei Li, Lingyi Chen, Shitong Wu +3
Reliable communication over a discrete memoryless channel with the help of a relay has aroused interest due to its widespread applications in practical scenarios. By considering th…
A Node-Based Polar List Decoder with Frame Interleaving and Ensemble Decoding Support
Yuqing Ren, Leyu Zhang, Ludovic Damien Blanc +5
Node-based successive cancellation list (SCL) decoding has received considerable attention in wireless communications for its significant reduction in decoding latency, particularl…
A Double Maximization Approach for Optimizing the LM Rate of Mismatched Decoding
Lingyi Chen, Shitong Wu, Xinwei Li +3
An approach is established for maximizing the Lower bound on the Mismatch capacity (hereafter abbreviated as LM rate), a key performance bound in mismatched decoding, by optimizing…
