Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Geometry and recovery of spectral-sparse signals
频谱稀疏信号 几何 恢复
2023/4/26
Spectral-sparse signals are those sparse in the Fourier domain and are very common in wireless communications, radar, sonar, medical imaging and other applications. Their recovery from noisy, limited ...
Quantum sensors, which detect the most minute variations in magnetic or electrical fields, have enabled precision measurements in materials science and fundamental physics. But these sensors have only...

Computer Engineering, Electronics, Information Sciences and Mechanical Engineering are the essential disciplines in Mechatronics and Robotics leading to powerful, compact and ever smarter systems. The...
It is a great pleasure to extend to you a warm invitation to join The 1st International Conference on Signals and Systems 2017 (ICSigSys 2017), to be held 16-18 May 2017 at Grand Sanur Hotel, in Bali,...
MONITORING HIGH-FREQUENCY OCEAN SIGNALS USING LOW-COST GNSS/IMU BUOYS
Global Navigation Satellite System (GNSS) buoys Inertial Measurement Unit (IMU) tide gauge
2016/12/1
In oceans there are different ocean signals covering the multi-frequencies including tsunami, meteotsunami, storm surge, as sea level change, and currents. These signals have the direct and significan...
Signals of selection in outlier loci in a widely dispersing species across an environmental mosaic
balancing selection candidate gene
2015/12/11
Local adaptation reflects a balance between natural selection and gene flow and is classically thought to require the retention of locally adapted alleles. However, organisms
with high di...
PROCESSING FULL-WAVEFORM LIDAR DATA:MODELLING RAW SIGNALS
lidar waveform analysis signal processing modelling generalized Gaussian
2015/11/10
Unlike airborne multi-echo laser scanner systems, full-waveform systems are able to digitize and record the entire backscattered signal of each laser pulse. It has been demonstrated that decomposing t...
Wavelet analysis of the LF radio signals collected by the European VLF/LF network from July 2009 to April 2011
Radio Network Wavelet precursors
2015/8/24
In 2008, a radio receiver that works in very low frequency (VLF; 20-60 kHz) and LF (150-300 kHz) bands was developed by an Italian factory. The receiver can monitor 10 frequencies distributed in these...
Application of empirical mode decomposition to very low frequency signals for identification of seismic-ionospheric precursor phenomena
Earthquake Precursor Phenomena Empirical Mode Decomposition
2015/8/24
This study investigates the application of empirical mode decomposition to signals from very low frequency transmitters in Europe that were received in Thessaloniki, Greece, to provide a method for de...
Multitone signals with low crest factor
Multiple frequency acoustic signal the peak coefficient bandpass crest factor
2015/8/13
Using some results from the recent mathematics literature, we show how to generate signals with perfect low-pass or bandpass spectra which have very low crest factors (under 6dB). An application to mu...

Simultaneous Generation Transmission Baseband Signals Employing Only Simple Single Electrode MZM
2015/7/15
Employing only a simple single electrode MZM, a novel hybrid access network, which is capable of generating and transmitting RF-vector (2.5-Gb/s QPSK at 60GHz) and baseband signals (1.25-Gb/s OOK) sim...
All Optical NRZ-to-RZ conversion for 43-Gbps Signals for Generation of 172-Gbps OTDM Signals Using Intersubband Transition MQW Optical Gate
Generation OTDM Signals Intersubband Transition MQW Optical Gate
2015/7/14
We demonstrate all optical NRZ-to-RZ conversion at a bit rate of 43 Gbps using an intersubband transition optical gate. The converted 2-ps RZ pulses were successfully applied to generate 172-Gbps OTDM...
