Synchronization is a key performance-limiting fac tor in any communication system and a challenging task to accomplish. In this paper, an energy detection based non data aided (NDA) algorithm for orthogonal pulse shape modulated (PSM) impulse radio ultra wideband (IR-VWB) system is pro posed. 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 & lSI) and with M-ary modulation. Simulation results are provided to demonstrate the performance of proposed algorithm.
International audienceTiming synchronization is a critical as well a challenging issue in ultra-wideband impulse radio (UWB-IR) due to their particular transmission characteristics. This letter proposes a rapid synchronization algorithm which can achieve frame-level synchronization in non-data-aided (NDA) mode. Relying on a unique transmit signal pattern based on orthogonal pulses and asymmetric modulation, synchronization is achieved without the need to search among thousands of bins, thereby significantly reducing the mean synchronization time. Simulation results prove that the proposed synchronization algorithm is efficient in single as well as in multi-user scenarios
