Abstract | Ultra wideband impulse radio (UWB-IR) technology is an ideal candidate for wireless UWB that can be utilized for short-range, high-speed, low power, and low cost indoor applications. The transmission gain of the free space propagation loss is usually estimated by using Friis' transmission formula. The Friis formula, it is not directly applicable to ultra wideband impulse radio network transmission systems, in particular the single band impulse radio, as the formula is expressed as a function of the frequency. Moreover, the waveform may be distorted due to the frequency characteristics of the antenna, and the comparison between Tx and Rx waveforms is not straightforward. This paper discusses the free space link budget evaluation of UWB antenna with template receiver based on the extended Friis' transmission formula. The template is considered at the receiver side to maximize the SNR for evaluation. An experimental evaluation of the complex transfer function needs the three-antenna method for the calibration of reference antenna. The technique gives very accurate results and is very useful for design and evaluation of UWB transmission performance, especially for the evaluation of waveform distortion effects. |

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.
