Abstract
Systems and methods provide for increasing time resolution in digital communication systems by properly processing several received signals transmitted in different bands or time slots. The received signals correspond to sub-signals that are obtained by performing a filter bank decomposition of a signal with high time resolution. The time resolution of the system is proportional to the inverse of the product of the number of sub-signals and their individual bandwidth. In the presence of additive white Gaussian noise, finer time resolution can be achieved by using the disclosed approach.
