| Abstract | Single-carrier modulation is currently regaining attractiveness for high-speed communications standards. Because of its robustness towards analog hardware impairments, single-carrier modulation can get along with low transceiver accuracy as compared to multi-carrier modulation. One hardware impairment that can, however, still seriously degrade the performance of single-carrier systems is amplifier non-linearity. The degradation is usually not as high as for multi-carrier modulation but can still not be neglected in practice. The pulse shaping at the transmitter, which is required for spectral mask compliance, will lead to power peaks in the transmitted signal that are clipped by the non-linearity. This paper presents an analytical approach for evaluating the performance degradation caused by non-linear amplifiers in single-carrier systems. The distortion due to the clipping is characterized by means of a discrete noise distribution. Numerical results show that this approximation allows for accurately predicting the performance degradation in terms of BER curves without extensive simulations. |

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.
