Gain control in radio chains of a receiver
First Claim
1. A method for automatic gain control of radio chains of a receiver, the method being performed by the receiver, the method comprising:
- receiving at least two radio frequency (RF) signals, each RF signal being received on an individual radio chain from an antenna array;
determining, by comparing the at least two RF signals to a threshold, whether to perform gain control or not of at least one of the at least two RF signals before analog combining of the at least two RF signals;
sending a notification to a detector regarding whether gain control is performed or not; and
performing analog combining of the at least two RF signals, thereby generating a single input to the detector.

Abstract
There is provided automatic gain control of radio chains of a receiver. At least two radio frequency (RF) signals are received. Each RF signal is received on an individual radio chain from an antenna array. By comparing the at least two RF signals to a threshold it is determined whether to perform gain control or not of at least one of the at least two RF signals before analog combining of the at least two RF signals. A notification is sent to a detector regarding whether gain control is performed or not. Analog combining of the at least two RF signals is performed, thereby generating a single input to the detector.

19. A receiver for automatic gain control of radio chains of the receiver, the receiver comprising a processing unit, the processing unit being configured to:
-
receive at least two radio frequency (RF) signals, each RF signal being received on an individual radio chain from an antenna array; determine, by comparing the at least two RF signals to a threshold, whether to perform gain control or not of at least one of the at least two RF signals before analog combining of the at least two RF signals; send a notification to a detector regarding whether gain control is performed or not; and perform analog combining of the at least two RF signals, thereby generating a single input to the detector. - View Dependent Claims (20, 21)

22. A non-transitory computer-readable medium comprising, stored thereupon, a computer program for automatic gain control of radio chains of a receiver, the computer program comprising computer program code configured to, when run on a processing unit, cause the processing unit to:
-
receive at least two radio frequency (RF) signals, each RF signal being received on an individual radio chain from an antenna array; determine, by comparing the at least two RF signals to a threshold, whether to perform gain control or not of at least one of the at least two RF signals before analog combining of the at least two RF signals; send a notification to a detector regarding whether gain control is performed or not; and perform analog combining of the at least two RF signals, thereby generating a single input to the detector.
