In this work, we propose an interference mitigation technique for ultrawide band (UWB)-impulse radio (IR) systems in the context of cognitive radio (CR). Such technique is based on the design of proper spreading sequences that introduce notch frequencies in both transmitted spectrum and matched filter (MF) receiver. In particular, binary, quaternary and polyphase direct sequence (DS) codes are proposed...
Interference suppression techniques for low complexity ultra wideband transceivers using pulse position modulation and energy detection receivers are proposed and evaluated. A theoretical framework is introduced, which enables the optimization of pulse shapes and energy detection integration windows based on a signal-to-interference-and-noise ratio criterion. Furthermore, the framework allows to incorporate...
