For example, when assessing short-term medication effects high frequency sampling may be appropriate, whereas relapse monitoring may require less intense sampling rates over longer periods of time.
Microfluidic flow cytometry generally permits higher sampling rate, less shear stress to cells, and less sample preparation steps than microscope-based cytometry.
Therefore, CS is regarded as a promising tool to conduct channel estimations, which may acquire and recover the sparse signal at less than the Nyquist sampling rate.
The SC allows calculating channel impulse responses with a sampling rate less than that required by Nyquist criterion, and hence is widely used in real-time wideband (e.g., >500 MHz) channel sounding for the fifth generation wireless communication scenarios.
While the work [25] develops a scalable channel state information (CSI) estimation with controllable resolution and complexity for future dense networks, the paper [26] studies the CSI estimation problem for a very wideband wireless channel using the sampling rate less than the Nyquist rate.
However, the estimated peak value P(ω i) is less dependent on the sampling rate and its biased estimate can be acceptable, even when frequency aliasing happens.
Such analysis requires a sampling rate less than the mean transit time of the contrast agent, the measurement of an individual arterial input function, the knowledge of the relationship between signal intensity and contrast agent concentration in the tissues and a pertinent mass transport model [ 48– 50].
Besides, this article also advocated that for short data records, whose sample points were less than 50 or the product of bandwidth and sampling period is less than 25, the preferred sampling rate was the twice of Nyquist rate.
Clearly, due to q < L the <span class="lh">sampling rate is less than rNYQ.
Under a fixed power, a larger sampling rate means less energy per sample, which might degrade the system performance.
