Abstract

Ultra-wideband technology finds various applications in radar technology, medical imaging, see-through-wall applications, surveillance and short distance communication applications. All of these applications require that the behavior of the channel be estimated giving a priori information about the various attributes of the channel like path loss, delay spread, channel capacity and so on. These parameters are the key to design an effective communication infrastructure suitable for the needs of the application.In this thesis, the main aim was to model the channel and extract the various parameters related to the channel through data processing methods. In particular, a classroom environment was chosen and various scenarios were considered. Channel Impulse Responses (CIR) were extracted for the scenarios using the CLEAN algorithm, Empirical RMS delay spread and mean excess delay values were calculated from the CIR’s. Values for path loss exponent and shadowing are also calculated. Based on the measurement data, the RMS delay spread and path loss have been modeled based on the probability density functions (PDFs) and the best distribution fits are provided. obtain the best distribution fits. The results obtained are compared with existing standards.
