Patent ID: 8724726

Claim:
A method for Automatic Gain Control (AGC) during a compressed mode search in a Multiple Input Multiple Output (MIMO) system, the method comprising: simultaneously determining power at a first frequency band using a first receiver connected to a first antenna and determining power at a second frequency band using a second receiver connected to a second antenna, the second receiver being in a compressed mode; when the second receiver changes from receiving the second frequency band to receiving the first frequency band, correcting the power determined at the first frequency band using the first receiver; and applying the corrected power determined at the first frequency band using the first receiver to the second receiver, wherein the correcting of the power determined at the first frequency band using the first receiver comprises: determining an average value of the power determined at the first frequency band using the first receiver of a predefined number of times and the power determined at the second frequency band using the second receiver of a predefined number of times; comparing the average value with at least one predefined threshold value; and based on the comparison result, correcting the power determined at the first frequency band using the first receiver.
