Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To increase the number of multiplex/transmission and to increase data transmission quantity by varying a transmission condition and enlarging the signal wavelength band of spread spectrum transmission. SOLUTION: Transmission data (a)-(n) inputted to data input parts 14a-14n are controlled by the variable control signals of various primary modulation types, which correspond to the transmission quality state of a transmission line 13 and are outputted from a control circuit 18 in spread modulation circuits 16a-16n and they are converted into parallel data. The variable control signals of center frequencies, which are outputted at the time of the primary modulation of the circuit 18 are sent to the circuits 16, the generation of carrier signals is controlled and the center frequencies are varied. Then, inadequate frequencies are avoided so that the center frequencies are not overlapped between transmission data and the optimum frequency is obtained.  It is received in a reception side unit 12 and a transmission signal multiplex/separation a spread separates the signal on the transmission line 13. Then, a spread spectrum demodulation circuit 20 executes a spread spectrum processing and executes primary demodulation and the original signal is obtained.
