Centralized RAN for Future Low-Power Wide-Area Networks: A LoRa Case Study
Joachim Tapparel, Amavi Dossa, El Mehdi Amhoud +1
In recent years, low-power wide-area network (LPWAN) technologies have gained significant traction as a connectivity option for Internet of Things (IoT) applications. While these n…
Reducing Power Consumption of Embedded Dynamic Memories with ECCs
Wenqing Song, Yifei Shen, Andreas Burg
Gain-cell embedded dynamic random-access memory (GCRAM) offers dense and energy-efficient on-chip storage, but retention-time variations force frequent refresh operations to cover…
High-throughput Low-latency Hardware Implementation of BCH Decoders
Jasper Lagendijk, Wenqing Song, Yunus Can Gültekin +3
Two well-known decoding algorithms for BCH codes are conventional decoding, based on the Berlekamp-Massey algorithm in combination with Chien search, and direct decoding, which use…
Lifted Gabidulin Construction for LDPC Representations of Finite Geometry Codes
Yifei Shen, Andreas Burg
Finite geometry (FG) codes combine the algebraic properties of classical block codes with the iterative belief propagation (BP) decoding ability of low-density parity-check~(LDPC)…
Maximum Coverage Chase Decoder for Optical Interconnects
Alessandro Cardinale, Wenqing Song, Bin Chen +3
We propose a low-complexity Chase decoder for optical interconnects that formulates test pattern selection as a generalized maximum coverage problem. For concatenated RS-BCH and oF…
Edge-Spreading Raptor-Like LDPC Codes for 6G Wireless Systems
Yuqing Ren, Leyu Zhang, Yifei Shen +4
Next-generation channel coding has stringent demands on throughput, energy consumption, and error rate performance while maintaining key features of 5G New Radio (NR) standard code…
