| Abstract | We propose an adaptive rate and power allocation algorithm for integrated voice and data services in a multiple input multiple output (MIMO) system. Given the available power at the MIMO transmitter is limited, the voice service is given the highest priority and appropriate power is allocated to satisfy the bit error rate (BER) requirement for voice transmission. Based on the remaining average power, optimal rate and power adaptations for maximum spectral efficiency under a BER requirement are performed for data transmission. We formulate the optimization problem based on m independent and identical single input single output optimization problems and solve for optimal rate and power adaptations. For voice transmission, a fixed rate transmission scheme and a channel inversion type power control policy are employed. For data transmission, an adaptive rate based on multilevel quadrature amplitude modulation (MQAM) scheme and a water-filling type adaptive power control are employed. Finally we study the performance of the proposed algorithms using analytical and simulation results |

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.
