sigma],[infinity]] function, then in the time interval [-T, T], T > 0 we need 2T([sigma]+[epsilon])/[pi] functional values, which is 2T[epsilon]/[pi] functional values more than in the case of recovery by using the optimal Nyquist rate [pi]/[sigma] of sampling, i.
The echo signals are demodulated to baseband and then sampled at a rate much lower than the Nyquist rate [F.
Suppose the echo signals are demodulated to baseband and sampled at the Nyquist rate [F.
4 shows a bandpass signals and its reconstructed versions from uniform samples at the Nyquist rate (which are non-invertible) for different iteration numbers.
Uniform sampling at the Nyquist rate for bandpass (or multi-band) signals may not be sufficient to recover the signal exactly.
CS is a new theory which enables the reconstruction of sparse signals to only a small number of linear measurements compared with traditional Nyquist rate
The function g is sampled at the Nyquist rate
