Autoregressive Models of the Random fields—A Survey

Hussein A. Abdulkadhim; Mayyadah S. Ibrahim; Ali N. Albu-Rghaif

Volume 20, Issue 2 , April 2020, Page 1-9

  Autoregressive (AR) random fields are widely use to describe changes in the status of real-physical objects and implemented for analyzing linear & non-linear models. AR models are Markov processes with a higher order dependence for one-dimensional time series. Actually, various estimation methods ...  Read More ...

Received 16 Aug 2019; Accepted 10 Dec 2019 Nonlinear Distortion Cancellation in Spatial Division Multiplexing System Based on RZ-Coded PCTWs Technique

Shahad S. Husain; Jassim K. Hmood

Volume 20, Issue 2 , April 2020, Page 47-57

  spatial division multiplexing (SDM) system has been considered as promising systems due to its ability to transport a higher bit rate for longer transmission distance. However, nonlinear phase noise (NPN (degrades SDM system performance. In this paper, we propose return-to-zero (RZ)-coded phase-conjugated ...  Read More ...

Robust Controller Design for Flexible Joint Based on Back-Stepping Approach

Ahmed Mohsen Mohammad; Shibly Ahmed AL-Samarraie

Volume 20, Issue 2 , April 2020, Page 58-73

  The objective of this paper is to design a robust controller for a system modeled as a two-mass system, with a flexible coupling. Here, the flexible Joint between two-mass systems is characterized by a spring. In fact, a two-mass system represents most of an industrial drive, like rolling mill drives, ...  Read More ...
