Abstract
The time division-synchronous CDMA TD-SCDMA uses time division duplex (TDD) for unsymmetrical data rate transmission, making conventional closed-loop automatic gain control (AGC) schemes impractical for TD-SCDMA receiver. An improved analog AGC algorithm used in TD-SCDMA receiver is presented, the general model is given and an equivalent linear system is proposed. Finally, the simulation and test results are given. The validity of the algorithm is verified by simulations and experiments.
