ABSTRACT:
A system and method is disclosed for enhancing a reception rate for a mobile communication system. A system is provided comprising a demodulator for separating a received signal into an I signal and a Q signal, an amplifier for amplifying the I signal and Q signal from the demodulator, and an offset adjusting unit. The offset adjusting unit is provided for amplifying an amplified I signal and an amplified Q signal, comparing a difference signal determined between the amplified I signal and the amplified Q signal with a target value, and outputting an amplification control signal associated with the difference signal and an amplification offset value.
