| Abstract(in English) | In software defined radio systems, it is desired to place the analog-to-digital converter (ADC) near the antenna part in the block diagram of the receiver, to improve the flexibility of the system. The radio frequency (RF) sampling method, in which the received signal is sampled at RF stage, realizes such structure. The RF sampling using the undersampling is a potential method to sample the RF signal using the existing consumer ADCs because the high speed ADC is required in the traditional methods, such as the nyquist sampling or the oversampling of the RF signal. This paper presents a technique to determine the minimum sampling frequency to undersample the separated multiple wireless systems simultaneously. In addition, this paper proposes a frequency selecting scheme which enables to select lower sampling frequency by receiving at least the desired transmission channels in the wireless system signals. This paper also provides the estimation of proposed scheme. |
