Recently, there has been increased interest in using Orthogonal Frequency Division Modulation (OFDM) systems in rapidly time-varying multipath environment. The performance of the systems in such time-frequency dispersive channels depends critically on the time-frequency localization (TFL) of the transmitter pulse. Biorthogonal Frequency Division Multiplexing based on Offset QAM (BFDM/OQAM) is an attractive modulation method since it allows time-frequency well-localized pulses at critical sampling (i.e. maximum spectral efficiency). In this paper we construct BFDM/OQAM system with Gaussian transmitter pulse and evaluate first-order and second-order statistics for the channel parameters in multipath time-varying channels.
