Energy Detection based Blind Synchronization for Pulse Shape Modulated IR-UWB Systems

International audienceSynchronization is a key performance-limiting factor in any communication system and a challenging task to accomplish. In this paper, an energy detection based non dataaided (NDA) algorithm for orthogonal pulse shape modulated (PSM) impulse radio ultra wideband (IR-UWB) system is proposed. Relying on unique signal structure, simple overlap-add operation followed by energy detection enables synchronization. The algorithm remains functional under practical scenarios i.e. in the presence of inter-frame and inter-symbol interference (IFI & ISI) and with M-ary modulation. Simulation results are provided to demonstrate the performance of proposed algorithm
