The Study On Modulation Recognition Based On Multi-Layer Perceptron

One of the main technologies in software radio is modulation and demodulation. It's the core of software radio study. With the development of communication technology, radio communication became more complex. Signals traveling in space with different modulation types as well as different frequencies fall in a very wide band (HF and VHF). Given a received communication signal that traveling in multi-signals and noise environment, the objective of modulation recognition is to decide the modulation type and estimate the modulation parameters of the communication signal without any priori knowledge about the signal information content. This is very important for analyzing and processing signal. It's the technology basic of common receiver and intelligent modem based on software radio.Based on previous research, the classification of communication signals with analogue modulations, digital modulations and the mixture of analogue and digital modulations is investigated in this dissertation.
