A motion-compensated spectrum-adaptive deinterlacing algorithm
2009 IEEE International Symposium on Circuits and Systems, 2009This paper presents a motion-compensated deinterlacing algorithm featuring spectrum-adaptive interpolation of interlaced field. Using motion-compensated reference pictures, the proposed spectrum-adaptive filter tactically identifies the baseband via spectrum analysis and removes the replicas of interlaced sampling, making overall algorithm adapt to ...

Compass tilt compensation algorithm using CORDIC
2008 IEEE International Symposium on Circuits and Systems (ISCAS), 2008In a 3-axis compass, the system tilt of the sensors needs to be compensated to calculate the heading of the compass correctly. A novel tilt compensation algorithm using the CORDIC algorithm is presented. Only five 2D-CORDIC operations are needed to ac quire the heading angle from three components of magnetic and acceleration data. This can be useful in

Parallel Compensation of Scale Factor for the CORDIC Algorithm
Journal of VLSI signal processing systems for signal, image and video technology, 1998The compensation of scale factor imposes significant computation overhead on the CORDIC algorithm. In this paper we present two algorithms and the corresponding architectures (one for both rotation and vectoring modes and the other only for rotation mode) to perform the scaling factor compensation in parallel with the classical CORDIC iterations.

On Genetic Algorithms Optimization for Heart Motion Compensation
2014Heart motion compensation is a challenging problem within medical robotics and it is still considered an open research area due to the lack of robustness. As it can be formulated as an energy minimization problem, an optimization technique is needed. The selection of an adequate method has a significant impact over the global solution. For this reason,

Neuron-Network-Based Nonlinearity Compensation Algorithm
2018 European Conference on Optical Communication (ECOC), 2018A simplified, system-agnostic NLC algorithm based on a neuron network is proposed to pre-distort symbols at transmitter side to demonstrate ∼0.6dB Q improvement after 2800km SMF transmission using 32Gbaud DP-16QAM.

Rain compensation algorithm for ACTS mobile terminal
IEEE Journal on Selected Areas in Communications, 1992The initial advanced communication technology satellite (ACTS) mobile terminal (AMT) demonstrations will involve two-way communications between the high-bit-rate link evaluation terminal (HBR-LET), which is a fixed terminal (FT), and a van-housed mobile terminal (MT).

Compensating for gain in objective quality estimation algorithms
2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004When objectively estimating speech, audio, or video quality, it is often necessary to compensate for the system gain or to "gain match" two or more signals. One can take three views of a system, leading to three different definitions of gain, and three different gain compensation solutions: one that minimizes distortion, one that matches input-output ...

A Selective Harmonic Compensation with Current Limiting Algorithm
2019This paper addresses a control algorithm to determine the reference currents indirectly from the grid voltages, taking into account the limited capacity of the power converter for compensating, entirely, the selected harmonic current. In previous works, the reference current was indirectly determined based on an average component correlated with the ...
