  • Method for timing recovery and compensation in time-division-duplex wireless communications
    Patent number: 6470057
    Abstract: In a synchronous code division multiple access (SCDMA) time division duplex (TDD) communication system, a remote terminal uses both open loop and closed loop techniques for synchronization with a base station. The timing of reception of information by tile remote terminal is performed with an open loop technique, while the timing of transmissions from the terminal is performed with a closed loop technique. Furthermore, a clock locked loop in the terminal compensates for differences between clocks of the terminal and the base station. The clock locked loop responds to signals from both the aforesaid open loop and closed loop techniques.
