Can compressed sensing beat the Nyquist sampling rate?
Data saving capability of “Compressed sensing (sampling)” in signal discretization is disputed and found to be far below the theoretical upper bound defined by the signal sparsity. On a simple and intuitive example, it is demonstrated that, in a realistic scenario for signals that are believed to be sparse, one can achieve a substantially larger saving than compressing sensing can. It is also s...
متن کاملSub-Nyquist rate ADC sampling-based compressive channel estimation
To realize high-speed communication, broadband transmission has become an indispensable technique in the nextgeneration wireless communication systems. Broadband channel is often characterized by the sparse multipath channel model, and significant taps are widely separated in time, and thereby, a large delay spread exists. Accurate channel state information is required for coherent detection. T...
متن کاملUltrasonic signal compressive detection with sub-Nyquist sampling rate
This study presents a compressed sensing (CS) based sampling approach for repetitive ultrasonic signal. Proposed system considers recovering ultrasonic signal with high equivalent sampling frequency from samples captured using analog-to-digital converter (ADC) clocked at a rate lower than Nyquist rate. A basis function is constructed to realize ultrasonic signal sparse representation, which pav...
متن کاملWireless Technology Recognition Based on RSSI Distribution at Sub-Nyquist Sampling Rate for Constrained Devices
Driven by the fast growth of wireless communication, the trend of sharing spectrum among heterogeneous technologies becomes increasingly dominant. Identifying concurrent technologies is an important step towards efficient spectrum sharing. However, due to the complexity of recognition algorithms and the strict condition of sampling speed, communication systems capable of recognizing signals oth...
متن کاملSub-Nyquist Sampling for TDR Sensors: Finite Rate of Innovation with Dithering
In this paper, Finite Rate of Innovation (FRI) is applied to time domain reflectometry and it is aimed at significantly reducing the data acquisition requirements. The sensitivity of FRI to quantisation noise is addressed given the stringent practical constraints on the resolution of the deployed analogue to digital converters in miniature reflectometry sensors. Dithering with averaging is prop...
