A detector circuit incudes a calculator circuit and a comparator circuit. The calculator circuit is configured to generate a plurality of first calculation values according to a plurality of first calculation symbols of a Pseudo-Noise Sequence and a plurality of second calculation symbols of a received signal, and generate a second calculation value according to the first calculation values. If a sign of a symbol of the Pseudo-Noise Sequence is the same to a sign of an adjacent symbol, the symbol is one of the first calculation symbols, and the second calculation symbols are corresponding to the first calculation symbols respectively. The comparator circuit is configured to generate a comparison result according to the second calculation value and a threshold value. The comparison result is configured for determining whether the detector circuit correctly receives the Pseudo-Noise Sequence.
