Abstract
A method is offered to detect a signal in mixture with noise analyzing a structure of the mixture “by partial intensity”. It is done by a reclassification of initial data in such a way every decimal digit becomes the top digit of a correspondent operational set. An embodiment of the invention offers a local television to switch on brightness of a dot on a screen of TV when a weak signal appears detected indirectly while no signal is directly observed in a mixture with a strong noise. Another embodiment of the invention offers mobile bearing by recognizing and processing two contrasted patterns of bearing. While a pattern of high intensity masks a pattern of low intensity, the task of bearing appears one to detect a signal in noise or under hindrance.
Claims11
Method to detect a signal in a mixture with noise received by a sensor, amplified and digitized by an analog-digital transformation into the stream of normalized fractions comprises:
- creating an artificial dimension of intensity represented with additional streams of data made each from similar parts of available fractions normalized like the initial ones comprising:
- creating partial fractions of the first additional stream by shifting out to the left and deleting the top digits of the fractions taken from the initial stream
- indexing the stream by the index 1
- creating partial fractions of the second additional stream similarly, shifting out to the left and deleting at the new stream the top digits of the fraction taken from the first additional stream
- indexing the stream by the index 2
- repeating two previous steps creating each next additional stream similarly:
- shifting out to the left and deleting the top digits of a fraction taken from a previous stream and indexing all streams accordingly
- stopping the procedure while the last significant digit of a fraction is reached
- establishing a procedure of a separate measuring each additional streams comprises:
- establishing a formula that need at least two arguments for computing
- establishing a sampling procedure to feed the formula with data taken from a stream by screening
- establishing a procedure to get an integrated measure for each stream
- establishing a procedure to take a decision and to detect a signal basing on said integrated measure
- providing a learning procedure comprises:
- adjusting measuring to supposed kinds of signals and noise
- establishing a threshold to get a decision by a value of a measure
- making visible an invisible signal after detecting comprises:
- switching on a current dot of a scanning circuit of a local TV if a signal is detected
- establishing brightness of the dot in an inverse accordance with the index of the stream of data that appears the first one detecting the signal and to get the less brightness the weaker the signal
