METHOD FOR RESAMPLING AT TRANSMISSION AND RECEPTION OF A DIGITAL SIGNAL WITH DIGITAL BAND TRANSLATION

摘要

The procedure carries out a resampling (25) in reception of a band-pass signal in which the signal is translated (4) to base-band with a configurable frequency and the resulting base-band signal is introduced into a decimator (5). Likewise, a resampling is carried out in transmission (26) where the base-band signal is interpolated (10) in order to be later on translated to band-pass (20) with a configurable frequency. The procedure permits correction of the frequency error introduced by digital-analog (11) and analog-digital (1) converters. Moreover, the proposed unit made up of band translation and resampling permits the complexity of the interpolation filters used for generating new samples of the digital signal to be simplified.
