| Abstract: | A method of dual carrier modulation and demodulation is presented. The digital Modem is designed based on Altera EPM7128S. The methods used in the design, the minimum bandwidth integer synchronous modulation and anti-jamming sample & judge memodulation, are emphasized. The application of this method in wheel-set and bearing failure detectors of passenger train is also illustrated. |
