Abstract

A mobile terminal and method for TDD mode wireless communication system comprises a receiver/transmitter device for receiving and transmitting radio frequency signals; a front end unit for selecting a receiver mode or a transmitter mode according to a control signal, and when set in the transmitter mode, sampling a signal to be transmitted to generate a sampling signal; and a baseband processing unit for providing the control signal to the front end unit, providing the signal to be transmitted to the front end unit in the transmitter mode, and generating a power compensation signal to adjust power of the signal to be transmitted outputted from the front end unit according to the sampling signal from the front end unit.
