Abstract
A transition signal generator is used to for controlling a booster of a time division duplex signal in a communications system. The transition signal generator includes a signal sampler for sampling the time division duplex signal, a power detector for detecting a power of the sampled signal, and a timing control unit for generating a logic signal indicating a direction of the sampled signal from the detected power of the sampled signal.
