<p>PROBLEM TO BE SOLVED: To reduce the circuit scale and power consumption of a reverse-spread apparatus which extracts data, conforming to prescribed codes from input signals inputted time-sequentially, by auto-correlation operations between the input signals and the codes. SOLUTION: This reverse-spread apparatus has an auto-correlation operation unit, which conducts a plurality of auto-correlation operations, in a time-shared manner between input signals and a plurality of types of data extraction codes CM0, CM1, CM2 and CM3, respectively to extract a plurality of types of data.</p> |
