1. A method of communicating comprising the steps of transmitting from a base station, during a DECT (Digital European Cordless Telecommuncation System) base station time slot of a DECT time frame, by modulating a base station data stream with a chip stream output of a chin sequence transmitter generator to provide rapid synchronization in compliance with DECT system timing constraints, a first spread spectrum signal to a user station;

  • receiving said first spread spectrum signal at said user station;

    transmitting from said user station, during a DECT mobile station time slot of said DECT time frame, by modulating a user station data stream with a chip stream output of a chip sequence transmitter generator to provide rapid synchronization in compliance with DECT system timing constraints, a second spread spectrum signal to said base station; and

    receiving said second spread spectrum signal at said base station.
