Therefore, the equalizer occupies the largest area in the 8-VSB demodulator. We propose a technique to reduce circuit area for 8-VSB equalizer by allocating multipliers with necessary bit length based on transmission line presumption using the result of correlation operation. The simulation results have shown that both circuit area and power consumption for multipliers are reduced by about 40％.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"66","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告システムLSI設計技術（SLDM）"}],"bibliographicPageStart":"61","bibliographicIssueDates":{"bibliographicIssueDate":"2006-05-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"41(2006-SLDM-125)","bibliographicVolumeNumber":"2006"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"created":"2025-01-18T22:57:30.406845+00:00","id":27045,"links":{}}
