An apparatus includes a plurality of received-signal registers (1, 2) which receive and store therein a plurality of respective received-signal sequences, a selector (3) which selects one of the received signal sequences stored in the received-signal registers (1, 2), at least one code register (4) which stores therein a de-spreading-code sequence, a multiplication circuit (5) which multiplies the selected one of the received-signal sequences by the de-spreading-code sequence, and a summation circuit (6) which obtains a sum of results of the multiplication to obtain a correlation between the selected one of the received-signal sequences and the de-spreading-code sequence. <IMAGE> |
