Synchronization is a performance-critical factor in most communication systems: from classical narrowband and emerging (ultra) wideband (UWB) point-to-point links to cooperative or ad hoc networking, where access must deal with multi-user interference (MUI) and possibly severe intersymbol interference (ISI). For universal applicability to all these scenarios, we develop a blind synchronization and...
In uplink orthogonal frequency division multiple access (OFDMA) systems, multiuser interference (MUI) occurs due to different carrier frequency offsets (CFO) of different users at the receiver. In this paper, we present a multistage linear parallel interference cancellation (LPIC) approach to mitigate the effect of this MUI in uplink OFDMA. The proposed scheme first performs CFO compensation (in time...
