Deblocking of Block-Transform Compressed Images Using Phase-Adaptive Shifted Thresholding
Many popular image compression schemes are based on block-transform coding, a technique where images are broken into small blocks of pixels prior to transformation and compression...

Dense 3D Reconstruction of Specular and Transparent Objects Using Stereo Cameras and Phase-Shift Method
In this paper, we first describe our approach to measuring the surface shape of specular objects and then we extend the method to measuring the surface shape of transparent object...

The Capacity of Noncoherent Continuous-Phase Frequency Shift Keying
Abstract—Capacity analysis is used to determine the fundamental tradeoff between power and spectral efficiency for coded continuous-phase frequency shift keying (CPFSK). The mod...

New Sequences Design from Weil Representation with Low Two-Dimensional Correlation in Both Time and Phase Shifts
For a given prime p, a new construction of families of the complex valued sequences of period p with efficient implementation is given by applying both multiplicative characters a...

Analog beamforming in MIMO communications with phase shift networks and online channel estimation
In multiple-input multiple-output (MIMO) systems, the use of many radio frequency (RF) and analog-to-digital converter (ADC) chains at the receiver is costly. Analog beamformers op...
