ABSTRACT:
A spread spectrum receiver includes a chip synchronization circuit controlling a phase of a spreading code for tracking synchronization at a phase control rate which is variable according to a rate control value. The rate control value is determined based on the signal-to-interference power ratio such that the phase control rate becomes lower as the signal-to-interference power ratio is reduced.
