| Abstract | This paper introduces a low-complexity antenna diversity receiver suitable for TDMA handset implementation. The receiver employs two branches of diversity, and is capable of adaptively choosing among three different diversity techniques which are implemented in a single design which we refer to as a multi-diversity receiver. It consists of a single conventional wireless digital receiver chain augmented with a few additional low-cost passive RF components and minor control circuits. We present algorithms for efficient co-phasing and equal-gain combining, as well as a novel cochannel interference-reduction combining algorithm. These are implemented in a system design simulation which conforms to the PACS (Personal Access Communication System) standard. We then present simulation link performance for selection diversity (SD), equal-gain combining (EGC) and interference-reduction combining (IRC) under Raleigh fading, flat fading with cochannel interference and selective fading conditions. The results show that EGC and IRC yield a signal-to-noise ratio (SNR) improvement of 1 dB and a signal-to-interference ratio (SIR) improvement 4 dB-/spl sim/5.5 dB, respectively, compared with SD. The receiver also lowers the irreducible word error rate due to multipath delay spread when the Doppler shift is small. These results are compared with the results from other research. |

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.
