Pilot‐Based Iterative Path Estimation and Maximum Ratio Combining (MRC)–Based Signal Detection of Orthogonal Time–Frequency Space (OTFS) Modulation for 6G in Fractional Doppler Channels

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
The sixth generation (6G) wireless networks are used to provide a large coverage, and also this generation needed to support different emerging applications in harsh areas with higher user equipment mobility. For the above case, a new modulation technique called orthogonal time–frequency space (OTFS) modulation has emerged as a promising technique to ...

Multiplicatively Repeated Non-Binary LDPC Codes [PDF]

, 2011
We propose non-binary LDPC codes concatenated with multiplicative repetition codes. By multiplicatively repeating the (2,3)-regular non-binary LDPC mother code of rate 1/3, we construct rate-compatible codes of lower rates 1/6, 1/9, 1/12,... Surprisingly,

ALOE-Based Flexible LDPC Decoder [PDF]

2010 13th Euromicro Conference on Digital System Design: Architectures, Methods and Tools, 2010
Radio communications terminals and infrastructure tend to support an increasing range of algorithms and radio access technologies. Flexible processing platforms are therefore needed for supporting multistandard or heterogeneous radios. Channel decoding is one of the most computing demanding digital signal processing blocks of a radio transceiver.

Dynamic Continuous Variable Quantum Key Distribution for Securing a Future Global Quantum Network

Advanced Quantum Technologies, Volume 8, Issue 10, October 2025.
The article explores securing a dynamic global quantum network using continuous variable QKD, proposing a unified three‐layer network architecture for integrating existing QKD networks. It evaluates secret key rates across various channels and introduces the link capacity as a metric for determining the optimum path for secret key distribution in a ...
