| Abstract | A unified framework was recently developed for optimizing the bit error rate (BER) incurred in the simultaneous differential modulation of the optical resources of polarization, phase, and/or amplitude, extending the conventional Stokes' parameters of polarization optics to a set of D2 generalized Stokes' parameters (GSPs). Novel optimal receiver structures were identified for multienergy polarization shift keying (POLSK), the optimality of differential phase amplitude shift keying (DPASK) and multichip differential phase shift keying (MC-DPSK) modulation formats was assessed, and optimal receivers for combinations of POLSK and DPSK were formulated. In this paper, the probability of error performance was evaluated for the newly introduced family of advanced modulation formats combining differential phase, polarization, and/or amplitude modulation, generically described as multichip differential state of POLSK. The symbol error rate and the BER for such systems are derived here in terms of the geometry of Stokes' signal space (the space of GSPs). The resulting formalism is applied to assess the performance of recently introduced MC-DPSK and MUB-coded systems (differential phase constellations based on maximally unbiased bases), as well as DPASK formats, establishing improved tradeoffs between sensitivity and spectral efficiency relative to conventional optical DPSK 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.
