Mobile phone for controlling diversity

A mobile phone to transmit and receive a radio frequency signal through a first antenna and a second antenna in a radio communication system, comprising:

• a first radio frequency signal receiving unit to convert the radio frequency signal received through the first antenna into a baseband signal to be transmitted to a controller;
• a second radio frequency signal receiving unit to convert the radio frequency signal received through the second antenna into a baseband signal to be transmitted to the controller;
• and
• a radio frequency signal transmitting unit to convert a baseband signal transmitted from the controller into a radio frequency signal to be transmitted to the first antenna or second antenna under control of the controller,
• wherein the controller controls transmission/receipt of the radio frequency signal, controls transmission/receipt diversity through selecting the first radio frequency signal receiving unit or second radio frequency signal receiving unit to control receipt diversity, and selecting the first antenna or second antenna to control the transmission diversity through the radio frequency is signal transmitting unit.
