WebOct 15, 2024 · Abstract: This paper describes that the mature ADC testing method with a simple test system using the incoherent sampling and the standard algorithm of windowing and FFT with 4Kpoint data can measure the SINAD of our target 12-bit SAR ADC accurately by proper setting of the input and sampling frequencies, which is industry-friendly. We … Weba high-speed RF signal using intelligent incoherent undersampling and signal reconstruction algorithms. Since the algorithm is based on incoherent sampling technique, the phase of the input signal, the sampling clock signal and the threshold signal do not have to be synchronized. This property simplifies the hardware setup for the signal testing. high gloss red concrete floors

WebMonte-Carlo Incoherent Sampling Design. Finding an optimal sampling scheme that maximizes the incoherence for a given number of samples is a combinatorial optimization problem and might be considered intractable. However, choosing samples at random often results in a good, incoherent, near-optimal solution. WebJun 17, 2010 · Incoherence plays an important role in CS and sparse signal approximation. Low-coherence guarantees that sparse recovery algorithms can exactly recover any sufficiently sparse signal and that this solution is unique. In CS, incoherence of the measurement matrix (related to the sampling in k – p space) is desired.
