| Summary: | The goal of this dissertation is to try to apply artificial intelligence algorithms
to the field of signal detection.
First, I studied and simulated the communication channel and common digital
communication modulations to construct the experimental environment. The traditional
signal detection algorithms are applied to the simulated channel to observe
the detection level of the traditional algorithm. These algorithms include:
Envelope Detection, Correlation Detection and Power Spectrum Detection. Then
Convolutional Neural Network (CNN) is mainly discussed, including the basic
thinking of CNN, the adjustment of various parameters for the neural network,
and the algorithm results.
Keywords: Artificial Intelligence Algorithms, Signal Detection, Modulations, Envelope
Detection, Correlation Detection, Power Spectrum Detection, Convolutional
Neural Network. |
