Abstract :
A SAW neural network processor for automatic recognition of two types of digital passband modulations is proposed in this paper. A feed-forward network with six hidden neurons is trained to recognize BPSK and MSK signals and the corresponding SAW NN modulation classifier is synthesised. Its performance is tested in the presence of additive white Gaussian noise. The influence of second-order effects in the SAW filters on the performance of the processor is also investigated. The results of this simulation show 95-99% probability for correct recognition at signal-to-noise ratio 10-12 dB.
