Implementation of Layered Decoding Architecture for LDPC Code using Layered Min-Sum Algorithm
International Islamic University Malaysia Engineering Journal, 2017 For binary field and long code lengths, Low Density Parity Check (LDPC) code approaches Shannon limit performance. LDPC codes provide remarkable error correction performance and therefore enlarge the design space for communication systems.In this paper ...

Transparent Topological Meta‐Diplexer via Tightly Confined Valley Surface States
Advanced Science, EarlyView.An optically transparent topological metasurface supporting tightly confined valley surface states enables robust and flexible wave routing in an ultrathin platform. A compact transparent meta‐diplexer with spatially and spectrally separated channels is realized, while communication experiments verify high‐fidelity signal transmission, opening new ...
