2. 1. Volterra Modeling and Estimation of the Human Smooth Pursuit

   Author : Viktor Bro; Alexander Medvedev; Geoff Chase; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volterra models; Volterra-Laguerre models; Nonlinear modeling; Smooth pursuit; Eye tracking; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Abstract : This thesis treats the mathematical modeling of the human smooth pursuit system using Volterra-Laguerre models. The smooth pursuit system allows for tracking of moving objects. Since it is a complex system including the muscles of the eye, nerves and certain parts of the brain, the system may be impaired if some part is compromised. READ MORE

5. 3. Characterization and Compensation of Hardware Impairments in Transmitters for Wireless Communications

   Author : Zain Ahmed Khan; Peter Händel; Magnus Isaksson; Mikko Valkama; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power amplifier; RF transmitters; SISO; MIMO; crosstalk; Volterra series; Volterra kernels; behavioral modeling; DPD; Ramanujan sums; multitone signals; I Q Imbalance; non-linearity; memory polynomial; density estimation; hardware impairments; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Increasing demands for data rate, energy efficiency and reliability in wireless communications have resulted in the introduction of radio frequency (RF) multiple input multiple output (MIMO) transmitters. However, MIMO transmitters suffer from additional crosstalk impairments along with the power amplifier (PA) and I/Q imbalance distortions observed in single input single output (SISO) transmitters.

7. 5. Behavioral modeling of wireless transmitters for distortion mitigation

   Author : Ali Soltani Tehrani; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear models; wireless communications.; computational complexity; I Q imbalance; digital predistortion; Volterra series; transmitter; power amplifier; Behavioral modeling;

   Abstract : As the demand for high speed and reliable wireless communication increases, theimportance of having a linear transmitter has enhanced. Distortions created by thetransmitter, such as power amplifier nonlinearity and I/Q imbalance, diminish thefidelity and limit the performance of wireless systems, if left undealt with. READ MORE
