| Abstract | The paper addresses the impact of the most common pulsed interference countermeasure, the pulse blanking, on the data demodulation stages of the GNSS receiver. Few works in the literature deal with this aspect, taking into account not only the $C/N_{0}$ drop but the impact of the coding strategy and the structure of the navigation message. In several works the structure of the navigation message is provided as a fact. The following paper investigates how some of the parameters (e.g. data rate) in Direct Sequence Spread Spectrum (DS-SS) systems could be optimized together with the pulse blanking parameters in order to improve the robustness to the interference in future evolutions of GNSS systems. After a brief general review of the DS-SS modulation, this paper will provide a description of the impact of the pulse blanking mitigation algorithm on the data demodulation performance for both un-coded and coded DS/BPSK systems. In particular, theoretical derivation of the expected Bit Error Rate (BER) will be provided. Theoretical derivation is supported by a set of fully software simulations, thanks to the use of a fully and flexible DS-BPSK system simulator developed during research activity. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
