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, the sampling frequency by which the generation of the interference can be removed is usually selected. However, in the method, the sampling frequency inevitably becomes large to avoid the interference. The paper proposes a new multi-signal detection technique in the undersampling system using an 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 suppressed. The principle of the technique and the receiver configuration are introduced and they are followed by numerical analysis of the performance based on the computer simulations. The effectiveness of the proposed system is discussed based on the results of the computer simulations.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_1_description_25":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14988/pa.2017.0000011141","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学理工学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Science
