| Abstract | The authors present the performance of an experimental TDMA (time division multiple access) portable radio link with a switching single loop frequency synthesizer. The synthesizer, used as a local oscillator (LO), operates around 2 GHz with a 400 kHz step size and can switch over 20 MHz in less than 400 mu s. Performance of the TDMA radio link using WER (word error ratio) as a criterion was measured with the synthesizer switching frequencies between bursts at the transmitter. WER versus SNR (signal-to-noise ratio) shows small degradation, only 0.5 dB at WER of 10/sup -3/, due to the phase noise of the synthesizer signal. The phase noise values for an offset of 10 kHz and 100 kHz were -70 dBc/Hz and -90 dBc/Hz, respectively. Measurements indicated that the radio link performance showed only minor degradation when the synthesizer was switched 20 MHz only 400 mu s before transmitting a data burst. This permits a handset to switch to different channels than the channel of operation to measure signal quality for possible call-transfer once every 2 ms frame. |

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.
