In the case of the uplink from the terminal to the CU, wireless links are established between the mobile terminals and DU. On the other hand, optical fibers are connected between the DU and CU. When PDM (Polarization Division Multiplexing) communication is used for optical communications, it is possible to construct multi-input multi-output (MIMO) channels in the fiber. In this configuration, both DU and CU need to detect MIMO signals, which causes severe signal processing delay. In this paper, to improve the responsiveness, it is assumed that the DU does not detect the signal but simply transfers, and only the CU detects the signal. At this time, it is effective to perform blind signal detection after unifying the wireless space and the optical space as one MIMO channel. This paper presents a novel method for demodulating in a CU using differential linear dispersion code (DLDC) to realize blind signal detection.","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":"10.14988/00029081","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_15":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"同志社大学ハリス理化学研究所","subitem_publisher_language":"ja"}]},"item_1_publisher_16":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Harris
