Performance Analysis of WiMax Receiver in presence of Ultra-Wideband System

Abstract

Ultra-wideband (UWB) signal with a large bandwidth has some advantages for instance multipath immunity, low transmission power, good resolution for ranging and detecting geo locations as well as restricting narrow-band interference. However, the main disadvantage is overlapping with existing narrowband-wideband cellular communication system operating simultaneously in the same area. WiMax is one of the 4G wideband cellular systems which are affected by narrowband UWB interference. Hence in this paper, path loss model and WiMax receiver characteristics have been determined to examine the coexistence issue between these two systems. Again, receiver sensitivity of different coding schemes and different antenna heights are considered to obtain the maximum cell radius with minimal interference.
