Learning While Transmitting: Pilotless Polar Coded Modulation for Short Packet Transmission
Geon Choi, Namyoon Lee
Short packets make channel learning expensive. In pilot-aided transmission (PAT), a non-negligible fraction of the packet is consumed by pilots, creating a direct pre-log loss and…

Multipoint Code-Weight Sphere Decoding: Parallel Near-ML Decoding for Short-Blocklength Codes
Yubeen Jo, Geon Choi, Yongjune Kim +1
Ultra-reliable low-latency communications (URLLC) operate with short packets, where finite-blocklength effects make near-maximum-likelihood (near-ML) decoding desirable but often t…

Hierarchical Subcode Ensemble Decoding of Polar Codes
Yubeen Jo, Geon Choi, Chanho Park +1
Subcode-ensemble decoders improve iterative decoding by running multiple decoders in parallel over carefully chosen subcodes, increasing the likelihood that at least one decoder av…
