But after learning more about compressed sensing, I’ve come to realize that, under the right conditions, both the claims and the theorem are true. The Nyquist-Shannon sampling theorem states that to restore a signal exactly and uniquely, you need to have sampled with at least twice its ...

Ifsymorderis'gray', the function uses a Gray-coded ordering. Data Types:char Desired separation between frequencies, specified in Hz. By the Nyquist sampling theorem,freq_sepandMmust satisfy(M-1)*freq_sep <= Fs. Data Types:double Number of samples per output symbol, specified as a positive...
By the Nyquist sampling theorem, freq_sep and M must satisfy (M-1)*freq_sep <= 1. Data Types: double nsamp— Number of samples per output symbol positive scalar greater than 1 Number of samples per output symbol, specified as a positive scalar greater than 1. Data Types: double Fs—...
Parseval's theorem states that the total energy for the N-sample window w(n) equals the sum of the squared magnitudes of the time-domain window samples or the integral over frequency of the squared magnitude of the Fourier transform of the window: ∫1/2−1/2∣W(f)∣2df=∑n∣w(n)...
To recover the message through a demodulator correctly, the Nyquist sampling theorem requires fs > 2(fc + f), where fs represents the simulation sampling rate, fc represents the carrier frequency, and f represents the highest frequency of the message signal. Typically, fc >> f. Modulation can...
For baseband signal, the sampling is straight forward. By Nyquist Shannon sampling theorem, for faithful reproduction of a continuous signal in discrete domain, one has to sample the signal at a ratefsfshigher than at-least twice the maximum frequencyfmfmcontained in the signal (actually, it is...
In this brief introduction to communication theory of Pulse Code Modulation (PCM) the key link--sampling (sampling theorem for low-pass, band-pass sampling theorem), simulation in MATLAB, for analysis and comparison of the results and final conclusions. Keywords: Communication simulation;Pulse Code...
The array with the number of steps for each delay, [NτNTNt], is handed over to the setdelaySteps function (line 24). Note that the resulting step sizes must satisfy the Nyquist–Shannon sampling theorem in order to resolve the resonance frequencies of the system [61], [62]. The ...
