文摘

This paper introduces a multichannel compressed sampling method for the multiband signals in the fractional Fourier domain, which is easy to be implemented with the mixing, convolution and low rate sampling. The paper constructs a representation for the fractional multiband signals, which is proved based on the fractional Fourier series. The results of simulation show the proposed system has better robustness and reconstruction accuracy compared with the classic MWC. The influence of the fractional order also be analyzed and simulated.
