“…These decisions will be suboptimal when d is small. We can avoid the problem of detection delay altogether if we adopt an off-line strategy known as interpolative timing recovery [14]. Instead of using the voltage-controlled oscillator (VCO) of a PLL to drive the sampling times, as shown in Figure 2, we could instead sample r (t ) asynchronously and uniformly with a free-running clock at a rate fast enough to avoid aliasing.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
