发明名称 METHOD FOR RESAMPLING AT TRANSMISSION AND RECEPTION OF A DIGITAL SIGNAL WITH DIGITAL BAND TRANSLATION
摘要 The invention relates to a method for resampling at transmission and reception of a digital signal with digital band translation. According to the invention, a resampling (25) is performed upon reception of a bandpass signal, whereby the signal is translated (4) to baseband with a configurable frequency and the resulting baseband signal is introduced into a decimator (5). In addition, a resampling (26) is performed upon transmission, whereby the baseband signal is interpolated (10) and, subsequently, translated to bandpass (20) with a configurable frequency. The inventive method can be used to correct the frequency error introduced by digital/analogue (11) and analogue/digital (1) converters. Moreover, the set formed by the band translation and the aforementioned resampling can be used to simplify the complexity of the interpolation filters used to generate new samples of the digital signal.
