Developments aimed at the software-defined-radio (SDR) concept for cellular applications received in creasing attention due to the necessity of multi mode/multi-system capable terminals for next gen eration cellular communication systems. This paper presents a highly reconfigurable DFE concept enabling multi-mode capable RF receivers for cellular appli cations. Its main functionality includes sample-rate conversion, channel filtering, and dynamic range con trol. The described partitioning enables shifting some of the functionality, normally located in the analog front-end (channel filtering, gain control) to the digital domain.
