<p>A system and method are provided for communicating in a borehole. In one example, the method includes receiving a baseband signal transmitted through a drill string using a plurality of elastic waves, where a spectrum of the baseband signal is duplicated after transmission due to oversampling. At least one passband is selected in order to recover the baseband signal from the duplicated spectrum. The baseband signal is decoded to recover a bit stream contained within the baseband signal.</p> |
