摘要： On the transmitter side of a spread spectrum communication device according to the present invention, transmission date are converted into a plurality of parallel data sets by a serial-parallel convertor and spread-spectrum-modulation is effected by means of PN code generators and selectors. Different modulated outputs are delayed by delay devices, using a sounder channel and the phase thereof as a reference. The delayed outputs and the output of the sounder channel are added by an adder, multiplexed and transmitted.On the receiver side correlation of a received signal with a reference signal is formed by a correlator and a correlation pulse is obtained from the correlation output. Data are reproduced by means of a sounder detecting circuit, a sampling pulse generating circuit and an information detecting circuit.In this way data reproduction can be effected with a high efficiency by means of a single correlator.

摘要： On the transmitter side, data to be transmitted are converted into a plurality of parallel data sets by a serial-parallel converter 101 and spread spectrum modulation is effected by means of PN code generators 105 and selectors 102. Each of the modulated outputs is delayed by a delaying circuit 103 with reference to a sounder channel and the phase thereof. The output thus delayed and the output of the sounder channel are added by an adder 104 to be multiplexed and transmitted.On the receiver side, correlation between a received signal and a reference signal is formed by a correlator 201 to obtain a correlation pulse from the correlation output thus obtained. Data demodulation is effected by means of a sounder detecting circuit 209, a sampling pulse generating circuit 210 and an information detecting circuit 211, starting from this correlation pulse.According to the structure described above, in SS communication, data demodulation can be effected with a high efficiency by using a single correlator.
