| Abstract(in English) | Software Defined Radio (SDR) technology has attracted attention because of its great flexibility as a multi-mode radio terminal. The undersampling system is developed as one of the technologies to achieve simultaneous reception of multiple radio systems using a single terminal. Generally in the undersampling system, the desired signal cannot be correctly demodulated when the other simultaneously received signal (=interference) overlaps or neighbors the desired spectrum in the frequency region after undersampling. Hence, sampling frequency by which the effect of such interference can be removed is usually selected, however, in such method, the sampling frequency therefore becomes large. The paper proposes a new multi-signal detection technique in the undersampling system using interference canceller. The scheme reduces the effect of the interference and, as the results of the reduction of the interference, the increase of the sampling frequency is overcome. The principle of the technique and the receiver configuration are introduced. Also numerical analysis on the performance of the proposed technique is discussed based on the results of the computer simulations. |
