UWB radio: Digital communication with chaotic and impulse wavelets

Kolumbán Géza, Krébesz Tamás

Research output: Contribution to journalArticle


Radio communications via channels already occupied by traditional telecommunication systems can be achieved by using ultrawideband (UWB) radio where extremely wideband wavelets are used in order to reduce the power spectral density (psd) of transmitted signal. Since the recovery of these UWB carriers is not feasible, noncoherent demodulation techniques have to be used. The letter evaluates and compares the noise performances of the feasible noncoherent UWB modulation schemes, namely, that of the noncoherent pulse polarity modulation and the transmitted reference system.
