N2 - Wireless personal area networks (WPANs) are drawing more and more attention recently, specially with the proposal of high rate technologies for its physical (PHY) layer. Multiband orthogonal frequency division multiplexing (MB-OFDM) ultra wideband (UWB) and direct-sequence (DS) UWB are the two technologies proposed for the PHY-layer in WPANs. Coexistence issue of the two aforementioned technologies while operating simultaneously in collocated WPANs, is a matter of concern, as they may induce mutual interference. In this paper, we address the channel estimation issue for DS-UWB receiver DEVs, in the presence of multi-user interference (MUI) and MB-OFDM interference. In fact, we use the minimum mean square error estimation (MMSE) to estimate the channel based on a pilot transmission scheme. Later, we employ the maximum likelihood (ML) criteria to detect the data symbols.
