Abstract
A receiver receives and demodulates a transmission signal that is modulated in Phase Shift Keying modulation and Direct Sequence Spread Spectrum using a spread code. The receiver includes a signal receiving unit that receives the transmission signal and outputs a received signal; a filter unit through which the received signal outputted by the signal receiving unit passes and is outputted as an outputted signal; a base band unit that is configured to despread the outputted signal based on a corrected despread code. The corrected despread code is generated based on the spread code and a deformation position, the deformation position indicating a position in the spread code at which deformation occurs as a result of the received signal passing through the receiver filter unit.
