Sub-Nyquist Bandpass Sampling

The work is devoted to an in-depth study of the aliasing process in sub-Nyquist bandpass sampling. The cluster nature of aliasing is revealed. Designations for clusters of aliases are proposed. Intracluster and intercluster aliasings are defined. The results obtained in this work will be used in the restoration of signals distorted by aliasing using the multi-channel multi-rate sampling developed by the authors.
