A matched filter has a circuit calculating an exclusive-OR of two input data, a circuit calculating an exclusive-OR of two codes corresponding to the two input data, respectively, and a correlation processor. The correlation processor, using the exclusive-OR of the two input data, one of the two input data, the exclusive-OR of the two codes, and the code corresponding to one of the two input data, calculates a correlation value of the two input data and the two codes.
