Frequency Estimation of Multiple Sinusoids with Three Sub-Nyquist Channels
Frequency estimation of multiple sinusoids is significant in both theory and application. In some application scenarios, only sub-Nyquist samples are available to estimate the frequencies. A conventional approach is to sample the signals at several lower rates. In this paper, we address frequency estimation of the signals in the time domain through undersampled data. We analyze the impact of un...
متن کاملA Survey on Sub-Nyquist Sampling
This paper gives a survey of sub-Nyquist sampling. Sub-Nyquist sampking is of great interest in the environment that sampling by Nyquist rate is infeasible due to either hardware or software limitation. The survey summarizes a number of recent important researches on sub-Nyquist sampling (compressive sensing). In addition to the basics of sub-Nyquist sampleing, including the fundamental theory ...
متن کاملFrequency Estimation of Multiple Sinusoids with Sub-Nyquist Sampling Sequences
In some applications of frequency estimation, the frequencies of multiple sinusoids are required to be estimated from sub-Nyquist sampling sequences. In this paper, we propose a novel method based on subspace techniques to estimate the frequencies by using under-sampled samples. We analyze the impact of under-sampling and demonstrate that three subNyquist sequences are general enough to estimat...
متن کاملImplementation of Sub-Nyquist Sampling System Based on Compressed Sensing
This paper describes the development of a sub-Nyquist sampling system that can digitize high-speed signals using a low-speed analog to digital converter (ADC). The system is implemented by a field programmable gate array (FPGA), and it is possible to make change to the equivalent sampling frequency according to the practical applications. As an application of the compressed sensing (CS) theory,...
متن کاملJoint Frequency Estimation with Two Sub-Nyquist Sampling Sequences
In many applications of frequency estimation, the frequencies contained in the signals are so high that the data sampled at Nyquist rate are hard to acquire due to hardware limitation. In this paper, we propose a novel method based on subspace techniques to estimate the frequencies by using two sub-Nyquist sample sequences, provided that the two under-sampled ratios are relatively prime integer...
