SPREAD SPECTRUM RECEIVER AND SPREAD SPECTRUM TRANSMITTER-RECEIVER USING THE RECEIVER

摘要

PURPOSE:To obtain the inexpensive receiver with simple configuration by using a super regenerative demodulator for broad band signal reception. CONSTITUTION:A spectrum is spread by a PN code, a sent signal is received by an antenna 11, demodulated by a super regenerative demodulator 13, the same PN code as that whose spectrum is spread is generated and the correlation with the PN code is taken by a correlation device 16, then the signal is decoded into an original base band signal. Thus, the spread spectrum receiver very immune to noise, having high sensitivity and simple configuration is provided at a low cost.
