PROBLEM TO BE SOLVED: To realize synchronization acquisition processing even under the limit of available memory quantity and under the limit of arithmetic quantity per unit time at the time of performing synchronization acquisition processing, in a system in which a plurality of slots exist in one frame and a plurality of synchronizing words exist. SOLUTION: Received data or the like are temporarily stored in respective buffers, and a fixed table is used in a prescribed timing, and the processing is divided by a primary processing means 22a, a secondary processing means 22b,... the N-secondary processing means 22c, a final processing means 22d, a normal processing means 22e, and an initialization processing means 22f. Thus, the composite correlation value of the received data and the fixed table is calculated, and the symbol synchronizing positions and the frame synchronizing positions are detected so that the slots can be corrected. Thus, it is possible to perform the synchronization acquisition processing even under the limit of the available memory quantity and under the limit of the arithmetic quantity per unit time. |
