This book is dedicated to Impulse Radio Ultra-Wideband (IR-UWB) communications, with a particular focus on 2PPM-TH-UWB systems. It proposes an adaptive approach based on a Multilayer Perceptron (MLP) neural network for the optimal estimation of the PPM shift (PPM-Shift), as well as a UWB waveform design method combining the Gaussian pulse and its derivatives, optimized by the Firefly algorithm. The results obtained over AWGN and IEEE 802.15.3a channels show an improvement in performance and spectral efficiency, while respecting the FCC emission mask.
