  • Patent number: 5467367
    Abstract: A telephone exchange system of this invention has a terminal connected to an extension by radio. As a radio communication modulation method, a spread spectrum method is used. A speech signal received from a line by the telephone exchange system is exchanged by an exchange switch, and is supplied to a data conversion unit. The data conversion unit causes a serial/parallel converter to covert a serial input signal into a parallel signal. The converted parallel signal is subjected to spread-spectrum modulation in units of parallel bits. The modulated signal bits are added to each other by an adder, and the sum signal is multiplexed on a carrier signal. The multiplexed signal is transmitted to the terminal. Upon reception of the signal, the terminal causes a phase synchronization circuit to generate an inverse spread code corresponding to a spread code, and synchronized with the reception signal, and inversely spreads the reception signal using the generated inverse spread code.
