LOCO Codes: Lexicographically-Ordered Constrained Codes

, 2019
Line codes make it possible to mitigate interference, to prevent short pulses, and to generate streams of bipolar signals with no direct-current (DC) power content through balancing.

Quantum codes derived from cyclic codes

, 2017
In this note, we present a construction of new nonbinary quantum codes with good parameters. These codes are obtained by applying the Calderbank-Shor-Steane (CSS) construction.

Fast list decoders for polarization‐adjusted convolutional (PAC) codes

IET Communications, 2023
A latest coding scheme named polarization‐adjusted convolutional (PAC) codes is shown to approach the dispersion bound for the code (128,64) under list decoding.

Timing and synchronisation for high‐loss free‐space quantum communication with Hybrid de Bruijn Codes

IET Quantum Communication, 2021
Satellite‐based, long‐distance free‐space quantum key distribution has the potential to realise global quantum secure communication networks. Detecting faint quantum optical pulses sent from space requires highly accurate and robust classical timing ...

Quantum Stabilizer Codes and Classical Linear Codes

, 1996
We show that within any quantum stabilizer code there lurks a classical binary linear code with similar error-correcting capabilities, thereby demonstrating new connections between quantum codes and classical codes.

Survival Outcomes and Complications Among Canadian Children With Retinoblastoma: A Population‐Based Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.

Space Frequency Codes from Spherical Codes

, 2005
A new design method for high rate, fully diverse ('spherical') space frequency codes for MIMO-OFDM systems is proposed, which works for arbitrary numbers of antennas and subcarriers.
