Abstract :
In this paper, we design a set of orthogonal waveforms which suppresses narrowband interferences (NBI) in ultra-wideband (UWB) communication systems. We use linear frequency modulation (LFM) and Hermite-Rodriguez basis functions. The problem is formulated as a semi-infinite quadratic optimization problem. Computationally efficient approach to solving the optimization problem is proposed. An example of multiple NBIs suppression problem is presented to illustrate the effectiveness of the proposed approach.
