| Abstract | In the context of satellite-based positioning, the problem of range-estimation with low resolution analog-to-digital conversion (ADC) is considered. While ADC with coarse output resolution degrades the positioning performance of Global Navigation Satellite System (GNSS) receivers, it's simplicity allows to realize sampling at high spatial and temporal rates in an energy and hardware efficient way. Therefore, here the achievable range-estimation accuracy of GNSS receive systems with 1-bit ADC resolution, multiple antennas and high receive bandwidths is analyzed. For different scenarios, including multi-path propagation and the presence of broadband interference, we investigate the scaling behavior of the estimation performance when increasing the number of receive antennas or the sampling rate. Results for all considered scenarios show that if a moderately higher number of antennas or a moderately faster temporal rate is used, 1-bit GNSS receive systems have the potential to outperform ideal receivers with infinite ADC resolution. This insight emphasizes that a receiver architecture with 1-bit ADC has the potential to play an important role for future low-cost receivers as well as for sophisticated energy efficient high-performance GNSS systems. |

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.
