Abstract :
This paper focuses on pulse shaping, modulation techniques, randomization by pseudo noise (PN) and other sequences, and power spectral density (PSD) shaping of ultra wideband (UWB) wireless communication signals and their effects on interference into and by other communication signals. The evolution of techniques proposed for these, and implementations based on research and development since the early 1990´s, to those that have been recently reported, are described and critically examined and discussed. The advantages and shortcomings of pulse shaping, modulation techniques, randomization, and spectrum shaping schemes, and their interference effects are compared and discussed for both the single and multiband (MB) cases, and a few illustrative plots are given
