Abstract :
Ultra Wideband (UWB) radios will unavoidably cause severe interference from the existing narrowband systems nearby. Therefore pulses are applied by forming notches at some frequencies as a way to suppress its interference. This paper present and compare two UWB pulses based on Chebyshev function approximation by using the Parks-McClellan (PM) algorithm and Prolate Spherical Wave Functions (PSWF) function by using Eigenvalue Decomposition (EVD) algorithm. The generated UWB pulses not only meet the Federal Communications Commission (FCC), but also mitigate single and multiple narrow-band interference (NBI).
