Although the bandpass sampling principles for a single RF signal is well developed, the method for sampling multiple bandpass signals is immature.
The conventional methods for obtaining valid sampling frequency of multiple RF signals need exhaustive tests or complicated graphs. A previous method is proposed to obtain valid sampling frequencies of multiple RF signals by using derived formulas in terms of some parameters (such as bandwidths and locations of the RF signals and so forth). However, it is not suitable for arbitrary signals unless one have previously derived the formulas for arbitrary signals by hand.
In this thesis, we propose an improved algorithm to obtain the valid sampling frequencies for arbitrary signals. The result can be used to efficiently find an appropriate range of valid sampling frequency for arbitrary signals.
