Abstract
A spread code shift controller circulates spread codes stored in coefficient registers and outputs the spread codes stored in a plurality of coefficient registers to a multiplier unit. A flag shift controller circulates one flag data on flag registers. As a result, flag data is sequentially input to receiving registers and a spread spectrum signal is stored for each data in the receiving registers. The spread spectrum signals stored in the receiving registers are input to corresponding multipliers and multiplied by the corresponding spread codes and the results of multiplication are added together in an adder unit to derive a correlation value.
