Abstract
A method and apparatus are provided for transceiving a signal. The method includes the steps of transmitting a superposed frequency component of the signal within each of a plurality of non-adjacent frequency bands, using analogue or digital filters within a receiver to suppress all signals outside the plurality of frequency bands and to pass a filtered signal within the plurality of non-adjacent frequency bands, determining a set of substantially non-uniformly spaced times at which the filtered signal within the plurality of non-adjacent frequency bands should be sampled and sampling the filtered signal at the determined times to provide sampled data. The method further includes the steps of Fourier transforming subsets of the sampled data, linearly combining the Fourier transformed subsets using a reconstruction matrix and extracting the signal from the linear combinations of the Fourier transformed subsets.
