| Abstract | We explore the potential of mathematically modelling the ultra-wideband (3.1–6.3 GHz) off-body radio channel using the same statistical distribution for corridor environments. Radio channel descriptive parameters of received signal strength, mean excess delay (τ mean) and root mean square (RMS) delay spread (τ RMS) are presented, modelled and compared for five indoor corridor environments. Statistical distributions for these corridors exhibit strong similarities despite each possessing starkly different geometrical and physical characteristics, and test arrangements. Each of the corridor environments was best modelled by the Rician distribution for the line-of-sight (LOS) received power and the Lognormal distribution for the non-LOS (NLOS) received power. Distribution of tmean was best modelled by the normal distribution for both LOS and NLOS scenarios. The distribution of τ RMS was likewise best modelled by the normal distribution for both LOS and NLOS arrangements. For corridors 1 and 2 (considered to exhibit the greatest differences), a finite element study was conducted to substantiate that the results cannot be dismissed as statistical anomalies created by the averaging effect over long journey paths. This work is relevant for the mathematical modelling of UWB off-body channel sounding in interior corridors and may reduce efforts required to model future indoor corridor variants. |

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.
