Sampling of communication systems with bandwidth expansion
Sampling of communication systems with bandwidth expansion
Many communication systems are bandwidth-expanding: the transmitted signal occupies a bandwidth larger than the symbol rate. The sampling theorems of Kotelnikov, Shannon, Nyquist et al. discussed by Unser (see Proceedings of the IEEE, vol. 88, no.4, p.569-87, 2000) shows that in order to represent a bandlimited signal, it is necessary …
