摘要： In the timing correcting device, a RAKE path detecting circuit 1 detects a plurality of path candidates to be tracked, from a reception signal, and outputs a “timing of a path” and a “detection correlation value” corresponding to each path candidate, as a result of the detection. Next, each tracking-path candidate deciding circuit (2a, 2b, 2c, . . . ) generates a predetermined decision standard that is necessary for selecting an optimum path timing from timings of the path candidates, based on an individually allocated result of the detection. Further, the tracking-path selecting circuit 3 selects a timing of an optimum path to be tracked, based on the result of the detection and the predetermined decision standards. Then, a comparator circuit 5 compares a predetermined reception reference timing given from the outside with the optimum path timing, and calculates a phase difference between the two. Last, the timing correction control circuit 6 controls a clock based on the phase difference, thereby to correct the reception reference timing.

摘要： A mobile station receives data from a plurality of sectors and selects sectors as candidates for site selection diversity transmit power control from the plurality of sectors. When the mobile station does not receive any data via dedicated physical data channels from selected sectors, the mobile station selects two or more sectors from sectors listed in a received sector selection candidate table.

摘要： A radio communication apparatus capable of solving a problem involved in a conventional apparatus in that in addition to a first receiver, a second receiver must be provided for establishing synchronization with a contiguous base station, which causes an increase in a circuit scale and consumed power of a mobile station. The present radio communication apparatus switches, when carrying out handoff from the current base station to a contiguous base station, a receiving frequency of a receiver from the frequency of the current base station to that of the contiguous base station, and a counter to be corrected by a synchronization manager from a first counter to a second counter that is used to establish synchronization with the contiguous base station.

摘要： A communication system includes a wireless IC tag and a reader/writer that performs reading and writing on the wireless IC tag via wireless communication. The reader/writer includes an error control encoder and an error control decoder. On writing data into the wireless IC tag, the reader/writer encodes the data by the error control encoder and writes real data separately from error-control-decodable data. On reading out data from the wireless IC tag, the reader/writer selects whether to read out only the real data or to read out data including error-control-decodable information to decode the data by the error control decoder based on error control information indicating whether to perform error control or not.
