| Abstract | Channel models are widely used to test receiver algorithms and, therefore, should model the propagation behavior as completely as possible. A promising type of channel model is the geometry-based stochastic channel model (GSCM), which represents the propagation channel by placing equivalent scatterers (ES) within a simulated geometry. Each of these ES is associated to a propagation path between the transmitter and the receiver. The propagation length of a modeled path can be calculated in a straightforward manner knowing the ES, the transmitter, and receiver locations by simple distance calculations. If the receiver is moving, an ES may change its location in order to model a propagation path accurately. However, this movement has not been sufficiently taken into account so far. Within this contribution, we show that the movement of an ES lies on a trajectory described by an ellipse or hyperbola when the receiver is in motion. Based on this derivation, a modeling approach for a propagation path resulting from multiple reflections is given, where at least one reflector is geometrically static in its position. Our description supports the simulation of an arbitrary receiver movement. Finally, we provide an example from an outdoor-to-indoor measurement campaign that confirms the movement of the ES. |

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.
