Abstract
A spectrum spreading receiver including a super-regenerative demodulator which is capable of receiving a spectrum spread signal and which is resistant to noise and has a wide band, resulting in being simplified in structure and decreased in manufacturing cost. A signal of which a spectrum is spread by a PN code is received by a receiving antenna and then demodulated by the super-regenerative demodulator. Then the same PN code as the PN code having carried out the spectrum spreading is generated and the correlation between the signal and the PN code is made by a correlation unit, resulting in the decoding of the spread signal into the original base band signal.
