PURPOSE:To provide the SS demodulator for multiple SS communication enabling efficient high-speed data transfer without deteriorating SS communication characteristics. CONSTITUTION:Serial transmission data is converted into parallel data by means of a serial-parallel converter 1 and applied to each parallel data multiplier 2-1 to 2-4. The data is diffused and modulated by a phase-corrected delay PN signal from delay devices 9-1 to 9-4 by the multipliers 2-1 to 2-4. Each modulation signal is delayed by delay devices 3-1 to 3-4, and added by an adder 5. The output is modulated with carrier wave by a multiplier 6, and transmitted. |
