| Abstract | In this paper, a hybrid modulation scheme called DDAWPPM (Differential Dual Amplitude-Width Pulse Position Modulation) suitable with wireless optical systems has been proposed, on the basic of DPPM (Differential Pulse Position Modulation), PAM (Pulse Amplitude Modulation) and PWM (Pulse Width Modulation). The combinations (DPPM-PAM) and (DPPM-PWM) have been proposed in previous works, but the proposed DDAWPPM and beside the symbol synchronization ability, it shows more improvement in term of data rate and spectral efficiency, on the other side it shows a degradation in term of power efficiency. We present theoretical expressions of spectral efficiency, power requirements, and the normalized data rate improvement, and we present comparison results to DPPM and the hybrids PAM-DPPM and PWM-DPPM. |

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.
