... convergence of zero points for monotone mappings or fixed points of pseudocontractions, see, for instance, 1–23 . In 1965, Browder 1 proved the existence result of fixed point for demicontinuous pseudocontractions ... a mapping of a linear normed space X into its dual space X ∗ . T is said to be hemicontinuous if it is continuous from each line segment in X to the weak topology i...

To reduce high-peak amplitude of interfering signal, the number of interfering pulses in any window interval ... values. Therefore, the number of interfering pulses in a window interval should be reduced to mitigate the effect of p-UWB interference on OFDM. BER performance was investigated for v...
