In the context of GNSS L5/E5a interference environment dominated by DME/TACAN and JTIDS/MIDS pulses, RTCA DO-292 [1] proposes to implement a temporal blanker mechanism to mitigate the detrimental impact of the pulsed interference signals on the nomin

Design of Iterative Demapping Schedules for Reduced-Complexity BICM-ID with Binary LDPC Codes and Orthogonal Modulations

Autor: Remi Chauvat, Matteo Paonni, Axel Garcia-Pena

Publikováno v: ISTC

LDPC-coded modulations are attractive solutions for many communications links. BICM provides a very simple, flexible yet effective way of combining binary channel codes with non-binary modulations. However, iterative demapping is sometimes necessary

Publikováno v: Proceedings of the 33rd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2020).

GNSS L5/E5a interference environment is dominated by DME/TACAN and JTIDS/MIDS pulses causing a degradation of the effective C/N0 observed by the receiver. A time-domain blanker is implemented to mitigate their impact. RTCA DO-292 proposes a model to
