Abstract :
The problem of frequency and frequency rate estimation from interrupted observations is addressed. The intuitive fact that the accuracy can be greatly improved by using separate observation intervals is quantitatively discussed. Cramer-Rao bounds and ambiguity functions are given and structures of maximum likelihood receivers are considered.
