It is shown that the density p of carriers plays an important role in accurately estimating the out-of-band energy of the signals based on the corresponding eigenvalues and in achieving a small out-of-band energy. We also show that p should be chosen such that rho ges 4 or rho ges 8. To perform numerically stable eigenanalysis, we employ the technique of singular-value decomposition.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_36": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Institute of Electrical and Electronics Engineers (IEEE)"}]}, "item_5_relation_15": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1109/WCNC.2008.178", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_16": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "Copyright © 2008 IEEE.
