| Abstract(in English) | In software defined radio systems, it is desirable to set the ADC nearer the antenna part in receiver block diagrams. The radio frequency (RF) sampling method, in which the received signal is sampled at RF stage, realizes such structure. The RF sampling using Nyquist sampling or oversampling requires a high speed ADC, because the ADC needs to sample the high frequency to convert to the digital signal. Therefore, we consider the undersampling scheme as a potential solution. Undersampling scheme is performed simultaneously conversion and sampling using a sampling frequency less than the Nyquist frequency of the sampled signal. This paper presents a sampling frequency selecting scheme to undersample the one system and oversample the other system, simultaneously. And this paper proposes a sampling frequency selecting scheme which is capable of calculating sampling frequency with speed and precision. At the end, this paper proposes a sampling frequency selecting scheme based on system-clock in multi-signal simultaneous reception. |
