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…
Code-Weight Sphere Decoding
Yubeen Jo, Geon Choi, Yongjune Kim +1
Ultra-reliable low-latency communications (URLLC) demand high-performance error-correcting codes and decoders in the finite blocklength regime. This letter introduces a novel two-s…
Rate-Matching Deep Polar Codes via Polar Coded Extension
Geon Choi, Namyoon Lee
Deep polar codes are pre-transformed polar codes that employ a multi-layered polar kernel transformation strategy to enhance code performance in short blocklength regimes. However,…
Sparsely Pre-transformed Polar Codes for Low-Latency SCL Decoding
Geon Choi, Namyoon Lee
Deep polar codes, employing multi-layered polar kernel pre-transforms in series, are recently introduced variants of pre-transformed polar codes. These codes have demonstrated the…
Nonlinear Self-Interference Cancellation With Learnable Orthonormal Polynomials for Full-Duplex Wireless Systems
Hyowon Lee, Jungyeon Kim, Geon Choi +3
Nonlinear self-interference cancellation (SIC) is essential for full-duplex communication systems, which can offer twice the spectral efficiency of traditional half-duplex systems.…
Deep Polar Codes
Geon Choi, Namyoon Lee
In this paper, we introduce a novel class of pre-transformed polar codes, termed as deep polar codes. We first present a deep polar encoder that harnesses a series of multi-layered…
Information-Theoretical Approach to Integrated Pulse-Doppler Radar and Communication Systems
Geon Choi, Namyoon Lee
Integrated sensing and communication improves the design of systems by combining sensing and communication functions for increased efficiency, accuracy, and cost savings. The optim…
Split-KalmanNet: A Robust Model-Based Deep Learning Approach for SLAM
Geon Choi, Jeonghun Park, Nir Shlezinger +2
Simultaneous localization and mapping (SLAM) is a method that constructs a map of an unknown environment and localizes the position of a moving agent on the map simultaneously. Ext…
