| Abstract | A new signal-space partitioning method is proposed for the calculation of transition probabilities of arbitrary two-dimensional (2-D) signaling with polygonal decision regions. This enables straightforward formulation of exact bit error probability, symbol error probability, mutual information (MI), and error probabilities of individual bits in the constellation. Previously published symbol error rate (SER) results for additive white Gaussian noise (AWGN) and various fading channels, diversity reception, and imperfect channel estimation (ICE) can all be used in conjunction with the new signal-space partitioning method to obtain the desired performance measures. Numerical results of the bit error rates (BERs) of several 8-ary and 16-ary constellations in AWGN and in Rayleigh, Ricean, and Nakagami fading channels with diversity reception are presented. Pilot-symbol-assisted 2-D signaling is also studied. The proposed new approach is both exact and numerically efficient. It provides new insights into the effect of bit mapping, constellation parameter optimizations, unequal error protection (UEP) at different bit positions, and performance comparisons of different constellations. |

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.
