<p>PROBLEM TO BE SOLVED: To provide a code division multiplex communication apparatus that can simply eliminate a time difference at output of symbol information in a correlator receiving a pilot channel and an information channel and to provide its transmission line correction timing control method. SOLUTION: The code division multiplex communication unit is characterized in that the unit identifies a time relationship of a spread code in a transmission line in response to a change in a spread ratio of the spread code, uses storage sections (queues) 111-11n of the FIFO system to manage a transmission line estimate value to properly conduct the estimate value by each spread ratio and adjusts a time difference at output of a correlator 211 between different spread ratios. Using the queue by each spread ratio can simply eliminate the time difference of outputs from correlators 211, 221 receiving the pilot channel and the information channel.</p> |
