To deliver data at hundreds of megabits per sec over wireless media with high accuracy requires high signal acquisition and synchronization speeds. Many techniques have been developed in the past and choice of a right synchronization technique has become user and application specific. In this paper, we present our recent progress on the development of synchronization techniques, first, by reviewing...
Synchronization is a challenging issue facing industrial designers that has not been researched often by academic researchers. The conventional techniques are phase-locked loop (PLL), digital PLL, or direct-digital synthesis (DDS). With any one or a combination of these techniques, high performance can be achieved at the expense of complexity or cost. In this paper, another technique, the injection...
In this paper for the first time the use of injection-locked phase-locked loop (ILPLL) for the BPSK to ASK coherent conversion is explored. Two circuit architectures are proposed, one using two second-harmonic ILPLL (SH-ILPLL) and the other using a single SH-ILPLL. In the case of two SH-ILPLL, feedback loop amplifiers are used and an increase of 20 times in the locking range of the converter is achieved...
