GAIN ADJUSTMENT STEPPING CONTROL IN A WIRELESS REPEATER
First Claim
1. A method for controlling gain in a wireless repeater, the method comprising:
- receiving an input signal at a receiving antenna of the repeater, the input signal being a sum of a remote signal to be repeated and a feedback signal resulting from a feedback channel between the receiving antenna and a transmitting antenna;
transmitting an output signal on the transmitting antenna, the output signal being an amplified input signal;
providing one or more gain control metrics, the gain control metrics being indicative of a loop gain of the repeater;
measuring the one or more gain control metrics; and
adjusting a variable gain of the repeater using a gain adjustment step size being a function of at least the loop gain of the repeater as measured by the one or more gain control metrics.

Abstract
A method for controlling gain in a wireless repeater includes providing one or more gain control metrics where the gain control metrics is indicative of a loop gain of the repeater; measuring the one or more gain control metrics; and adjusting a variable gain of the repeater using a gain adjustment step size being a function of at least the loop gain of the repeater as measured by the one or more gain control metrics. In another embodiment, the gain control algorithm block is configured to divide the loop gain of the repeater into multiple gain adjustment control zones. The gain adjustment control zones may include a first zone having a loop gain in a stable operating region and a second zone having a loop gain outside the stable operating region.

12. A wireless repeater having a receiving antenna for receiving an input signal and a transmitting antenna for transmitting an output signal, the input signal being a sum of a remote signal to be repeated and a feedback signal resulting from a feedback channel between the receiving antenna and the transmitting antenna, the output signal being an amplified input signal, the repeater comprising:
-
a gain control block configured to control a variable gain value of the repeater based on one or more gain control metrics, the gain control metrics being indicative of a loop gain of the repeater, the gain control block comprising a gain metric calculator configured to generate the one or more gain control metrics and a gain control algorithm block configured to control the variable gain of the repeater based on the plurality of gain control metrics, wherein the gain control algorithm block is configured to adjust the variable gain of the repeater using a gain adjustment step size being a function of at least the loop gain of the repeater as measured by the one or more gain control metrics. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
