Ultra-Wideband Digital Receive Method Based on Low-Speed Analog-to-Information Sampling
Abstract
the received signal has sparse frequency spectrum in short time. The ultra-wideband digital receive method based on Analog-to-Information
is proposed in this paper, which can obtain the capability of wideband digital receiving by low-speed sampling. Firstly, the analog signal is
modulated by pseudo-random signal; next the signal is filtered by low-pass filter and sampled with low speed ADC; and then the original signal can be reconstructed by orthogonal matching pursuit algorithm. Finally, the simulation demonstrates that the original signal can be recon-structed even that the sampling speed goes down 8 times.
