Abstract
A method and device for converting at least one narrow band RF signal, being suitable for transmission between at least one communications device suitable for receiving wide-band RF signals and at least one base station, to baseband. The method includes directly down-converting a signal spectrum including the at least one RF narrow-band signal to baseband such that the at least one narrow-band RF signal results at a low intermediate frequency (IF). And, digitally phase rotating the down-converted signal spectrum such that the at least one narrow-band RF signal is phase rotated from the low-IF to baseband.
