In the technique, the existence of the transmitted confidential signal is hidden to the anyone other than the legitimate receiver. In this paper we propose a new wireless steganography technique using the spectrum spreading approach. We evaluate the transmission performance of the embedded secret signal and the anti-attacking performance against eavesdroppers by computer simulation. As a result of the evaluation, we clarify the requirements of the various parameters of the technique by which signal detection by third-party eavesdroppers is made almost impossible.","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.2017.0000013589","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
