Embodiment Construction

[0068] The technical solution and implementation process of the present invention will be described in detail below in combination with specific examples.

[0069] The communication radiation source signal classification and identification method of the present invention comprises the following steps:

[0070] Step 1: Transmission and reception of communication radiation source signals;

[0071] The schematic diagram of the transmission and reception process of the communication radiation source signal is as follows: figure 1 As shown, the modulated signal is amplified by the power amplifier of the communication radiation source (hereinafter referred to as "power amplifier") and then transmitted by the transmitter. After receiving the signal, the receiver samples and receives it and outputs the received signal.

[0072] The input signal to the power amplifier is

[0073]

[0074]Among them, n is the sampling point, the value range is from 1 to N, N represents the total nu...

Abstract

The invention provides a communication emitter signal classification and identification method under the condition of Gaussian white noise channel, which comprises the following steps of transmittingand receiving the communication emitter signal; extracting envelope information from the received signal of the communication emitter; constructing the characteristic data set dictionary of communication emitter signal; classifying and identifying the received signals from untagged communication emitters. On the premise that the labeled signal characteristic dictionary database is artificially continuously supplemented and perfected, the invention can realize very good classification and identification of the communication emitter signal under the condition of Gaussian white noise channel.

Description

technical field [0001] The invention relates to wireless communication and signal processing technology, in particular to a method for classifying and identifying communication radiation source signals. Background technique [0002] With the continuous development of communication technology, the reconnaissance and anti-reconnaissance in the communication field, the struggle against interference and anti-interference intensified, and related technologies have developed rapidly. Although the current international situation maintains an overall peaceful and stable situation, with the adjustment and implementation of the U.S. military’s return to the Asia-Pacific strategy, once a war breaks out in this direction, it will be a highly informatized land-sea-air joint operation against the background of strong enemy intervention. At that time, the implementation of command and control and the application of combat power by potential opponents will be highly dependent on wireless co...
