Analysis on the Application of the Over-sampling Technology in the Communication Signal Processing

When dealing with communication signals before the signal transmission, the modulation signal is given priority to the periodic signal, so the modulated signal already have the characteristics of the cyclical before sending actually.In order to simplify the process, the signal hypothesis is generally for stationary signal, however in practice, the communication signal is already with stability and circularity.Through over-sampling, it can make the received signal to be cycle stability, and can reflect the change of signal statistics in time, making up for the deficiency of the stationary signal on the processing method.This article will focus on the application of the over-sampling technology in the communication signal processing.
