Embodiment Construction

[0030] The inventive concepts will now be described more fully hereinafter with reference to the accompanying drawings, in which certain embodiments of the inventive concepts are shown. However, the inventive concepts may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and The scope of the inventive concept will be fully conveyed to those skilled in the art. Throughout the description, like numbers refer to like elements. Any steps or features shown in dashed lines should be considered optional.

[0031] Generally, in existing receivers in radio access network nodes and portable wireless devices, the RF signal from a separate receiver branch is converted to baseband and then converted to Digital signal. The digital signal is then monitored and it is determined whether a gain change of the signal is re...

Abstract

Automatic gain control of the radio chain of the receiver is provided. At least two radio frequency (RF) signals are received. Each RF signal is received on a respective radio chain from the antenna array. By comparing the at least two RF signals to a threshold, it is determined whether to perform gain control on at least one of the at least two RF signals prior to analog combining the at least two RF signals. A notification is sent to the detector as to whether gain control is performed. An analog combination of at least two RF signals is performed to generate a single input to the detector.

Description

technical field [0001] Embodiments presented herein relate to automatic gain control, and in particular to a method, receiver, computer program and computer program product for automatic gain control of a radio chain of a receiver. Background technique [0002] In communication networks, achieving good performance and capacity can be challenging for a given communication protocol, its parameters, and the physical environment in which the communication network is deployed. [0003] For example, one parameter in providing good performance and capacity for a given communication protocol in a communication network is the capability of the radio transceiver equipment operating in the communication network. Examples of such radio transceiver devices include radio access network nodes and portable wireless devices. For example, a radio transceiver device includes a receiver to receive signals from another radio transceiver device or node in a communication network. [0004] As kn...
