Error Propagation Mitigation in Sliding Window Decoding of Braided Convolutional Codes

, 2020
We investigate error propagation in sliding window decoding of braided convolutional codes (BCCs). Previous studies of BCCs have focused on iterative decoding thresholds, minimum distance properties, and their bit error rate (BER) performance at small to

Ultra‐Compact Waveguide Couplers for All‐Silicon Terahertz Platform

Advanced Photonics Research, Volume 7, Issue 1, January 2026.
Compact all‐silicon couplers are developed to enable efficient mode conversion between dielectric and metallic hollow waveguides in integrated terahertz systems. By combining dielectric rod coupling and slot confinement, the design achieves strong mode matching within a very short footprint while maintaining mechanical robustness. The couplers preserve

Improving 3D-Turbo Code's BER Performance with a BICM System over Rayleigh Fading Channel [PDF]

Radioengineering, 2016
Classical Turbo code suffers from high error floor due to its small Minimum Hamming Distance (MHD). Newly-proposed 3D-Turbo code can effectively increase the MHD and achieve a lower error floor by adding a rate-1 post encoder.

Tunable Topological Directional Supercoupler and Applications in THz On‐Chip Communication

Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
A topological directional supercoupler is demonstrated, enabling dual‐channel 50 Gbps on‐chip terahertz communication with phototunable power splitting ratios. The achieved sub‐wavelength scale coupling area, sharp waveguide bends, and momentum‐conserved coupling process allow for ultra‐compact and efficient terahertz topological photonic integrated ...

Minimum Bit-Error Rate Design for Space-Time Equalisation-Based Multiuser Detection

, 2006
A novel minimum bit-error rate (MBER) space–time equalization (STE)-based multiuser detector (MUD) is proposed for multiple-receive-antenna-assisted space-division multiple-access systems. It is shown that the MBER-STE-aided MUD significantly outperforms
