Patent ID: 7602865

Claim:
A system for enhancing a reception rate for a mobile communication device, the system comprising: a demodulator for separating a received signal into an I signal and a Q signal and then outputting the separated I and Q signals; an amplifier for amplifying the separated I and Q signals and outputting the amplified I and Q signals, each of the amplified I and Q signals having a power level value and an offset value; and an offset adjusting unit for: detecting the power level value and the offset value of the amplified I signal and converting the detected power level and the offset value to a first digital power value and a first digital offset value using a first analog to digital converter, detecting the power level value and the offset value of the amplified Q signal and converting the detected power level and the offset value to a second digital power value and a second digital offset value using a second analog to digital converter, calculating a difference value by comparing the first digital power level value and the second digital power level value with a target power level value, calculating an amplification offset value based on the first digital offset value and the second digital offset value, and outputting an amplification control signal associated with the difference value and the amplification offset value.
