Abstract: 3G terminal reconfiguration can be realized by relying on the software-defined radio technologies. Among them, both fast digital signal processing technology and high-performance radio frequency data collection are the key technical issues. This paper focuses on the processing method of frequency spectrum aliasing when frequency spectrum aliasing appears under the situation of under-sampling of radio frequency signals. The truncation frequency spectrum approach is used, simultaneously; it analyzes the influence of the truncation treatment and frequency spectrum aliasing on signal restoration. Finally, the paper discusses in detail the relations between the spectrum truncation filter cutoff frequency and under-sampling frequency and the signal-to-noise ratio.
