摘要： PROBLEM TO BE SOLVED: To simplify the control of parallel de-spreading of a common redundant hard resource by reducing the number (circuit scale) of redundant hard resources which perform de-spreading when updating the path timing, in CDMA receiving device and its path timing update control method. SOLUTION: A path timing reported by a searcher portion 3-1 is stored in a buffer memory 3-21, and a slot number for which de-spreading is performed by individual resources 3-41 to 3-4M is acquired from a slot counter 3-24, and a slot having a number which is the acquired slot number plus the number of slots L which need processing for preparing path updating is determined as a path update slot. Then, a de-spreading code of the path update slot is created by a slot boundary code initial value generating circuit 3-25. Using an initial value of the de-spreading code, only one slot de-spreading of the path update slot is performed in a new path timing by a redundant resource 3-3, and subsequent de-spreading is continuously performed by the individual resources to restore the redundant resource.

摘要： PROBLEM TO BE SOLVED: To remarkably reduce circuits and wirings by performing time multiplexing to the 6-bit transmission powers of plural channels. SOLUTION: All the 6-bit transmission powers sent from a control part to respective first to n-th channels are sent to a power multiplexing control circuit 21, wherein time multiplexing is performed by a clock having the n-times speed of the highest symbol rate among Ich and Qch data. Time-multiplexed (n) pieces of total time which are coincident with the time width of the transmission power of the first channel as the highest symbol rate. Thus, by performing time multiplexing to the transmission powers (6 bits) of all the channels, a transmission power selector 22 can be made common for all the channels so that the more the number of channels is increased, the more the circuits and wirings can be reduced. Further, by replacing a transmission power table with a transmission power ROM, the transmission power selector can be eliminated as well, and the circuits and wirings can be reduced.

The auxiliary data is such that a proportion of 0s to 1s is made to be 1 to 1 including the synchronization data, or a proportion of 0s to 1s is made to be closer to 1 to 1 including the synchronization data than a proportion of 0s to 1s in the synchronization data. The transmitting side transmits the synchronization data and the auxiliary data by using a transmission unit 4. A receiving side receives the synchronization data and the auxiliary data by using a receiving unit 7, and adjusts an equalizer 8 on the basis of the synchronization data and the auxiliary data.
