US 2011/0215856 A1 · Method And Apparatus For Automatic Gain Control for Nonzero Saturation Rates

Abstract

A method for automatic gain control comprising the steps of measuring a signal using compressed sensing to produce a sequence of blocks of measurements, applying a gain to one of the blocks of measurements, adjusting the gain based upon a deviation of a saturation rate of the one of the blocks of measurements from a predetermined nonzero saturation rate and applying the adjusted gain to a second of the blocks of measurements. Alternatively, a method for automatic gain control comprising the steps of applying a gain to a signal, computing a saturation rate of the signal and adjusting the gain based upon a difference between the saturation rate of the signal and a predetermined nonzero saturation rate.

Dependent claims

A method for automatic gain control comprising:

splitting a signal into consecutive blocks;
applying a measurement matrix to each said block separately to produce a plurality of measurements for each consecutive block;
indexing each successive block of measurements;
applying a window to each successive block of measurements;
applying a gain to a block of measurements;
quantizing said block of measurements to produce a set of output measurements;
calculating a saturation rate of said block of measurements;
and
calculating a new gain to apply to a next block of measurements by adding an error between a desired non-zero saturation rate and said computed saturation rate of said block to said gain.
