This paper describes a digital-to-time converter (DTC) architecture that can be used as a fine interpolator in a time-to-digital converter (TDC) or as an adjustable delay in clock deskewing, for example. The new architecture of the DTC achieves adjustable sub-ps-level resolution with high linearity in ns-level dynamic range. The propagation delay adjustment is implemented by digitally controlling...
In this paper, a new scheme for delay estimation of multipath components in a direct-sequence spread spectrum system is presented. The proposed scheme is based on a conventional energy detector followed by an independent component analysis (ICA) algorithm. The ICA algorithm effectively decomposes the received signal into the independent paths and noise term and hence provides information about the...
