摘要： An orthogonal frequency division multiplexing (OFDM) demodulating apparatus includes a delay profile creating section, a Fourier converting section, a pilot signal extracting section, a transmission path characteristic estimating section, an inverse Fourier converting section, and a window control section. In this case, the window control section creates a delay profile for defining a calculation range by leaving a path which exists at a same position in both the delay profiles created by the delay profile creating section and the inverse Fourier converting section and the number of times of detection which is equal to or higher than a threshold value and defines a higher threshold value for the path at a predetermined position from the position of the main path within the delay profile created by the inverse Fourier converting section than for the paths at the other positions.

摘要： A registration/search method for structured documents where correspondence data is prepared between a fixed-length-string and a string occurrence position within a structured document for all fixed-length-strings in the document and for each structured document. A list of a character and all hierarchical elements containing the character and element lengths is prepared. An occurrence frequency and an occurrence position of a search term is obtained using the plurality of fixed-length-substrings and the occurrence frequency extracting index. A search character is selected from the search term. A hierarchical element containing the search character is obtained using the character from the element length index. A length of the element corresponding to a search range is extracted using the obtained occurrence position. A matching degree for the search term is calculated from the obtained occurrence frequency of the search term and the extracted element length of the element corresponding to the search range.

摘要： A document search method and apparatus and a portable medium used therefor are described, in which when registering a document in a data base, the logic structures of each document to be registered are superposed one on another to generate a structure index in which the structure elements having the same position of occurrence in the document are represented by a single meta-node. At the time of document search, a mass of the meta-nodes meeting a specified structural condition is determined with reference to the structure index. A string index is searched with the meta-node identifiers as a key thereby to determine a mass of documents meeting the specified condition. As a result, a highly accurate structure-specified search is made possible on a document data base including a mass of structured documents. In the structure-specified search of structured documents, the conditions for the position of occurrence of the logic elements in the document are specified, thereby making possible a highly accurate structure-specified search.
