Modeling and Analysis in Frequency of the UWB Channel with Lognormal Statistics for MB-OFDM Systems

In this paper, the ultra-wideband channel with multiband orthogonal frequency division multiplexing (MB-OFDM-UWB) is analyzed in the frequency domain. For UWB channels with lognormal small-scale fading in time domain, we obtain closed analytical expressions for the parameters that model the sub-carr...
