evolving models have found applications in many real world systems. in this paper, potentials of the evolving linear models (elms) in tracking control design for nonlinear variable structure systems are introduced. at first, an elm is introduced as a dynamic single input, single output (siso) linear model whose parameters as well as dynamic orders of input and output signals can change through ...

This paper presents the PI controller design for coupled tank as Single Input Single Output (SISO) process using Characteristic Ratio Assignment (CRA) method.CRA is an approach to directly control the transient response of linear time invariant control systems. The transient response for all pole transfer function of n order system can be controlled by introducing a set of parameters(αi) charac...

In this paper, we focus our attention on linear time invariant continuous time linear systems with one input and one output (SISO LTI systems). We consider the problem of constructing a reduced order system via truncation of the original system. Given a SISO strictly proper transfer function T (s) of McMillan degree N and a strictly proper SISO transfer function T̂ (s) of McMillan degree n < N ,...

In this paper, we revisit the forward, backward and bidirectional Bahl-Cocke-Jelinek-Raviv (BCJR) soft-input soft-output (SISO) maximum a posteriori probability (MAP) decoding process of rate-1 binary convolutional codes. From this we establish some interesting explicit relationships between encoding and decoding of rate-1 convolutional codes. We observe that the forward and backward BCJR SISO ...

In the past, from a signal processing perspective, most wireless networks have been Single Input and Single Output (SISO), with the sequential nature of SISO signal processing serving as a bottleneck that limits performance. However, processing multiple signals simultaneously through smart antennas could lead to substantial performance improvement. Using this new approach, researchers are explo...

Low-complexity soft-in soft-out (SISO) equalizers based on time-varying linear filters and soft inter-symbol interference cancellation are known to be a viable alternative to the optimal trellis-based SISO equalizers when used in receivers based on iterative equalization and decoding. In particular, when the signal constellation is large and/or the channel impulse response is long, the computat...

In this contribution, the On-body propagation measurements at 40m underground mine gallery and their statistical analysis are presented. Monopole antennas were installed on the body in order to form three on-body channels, namely belt-chest, belt-wrist and belt-head. The channel parameters of a 2 × 2 Multiple-Input Multiple-Output (MIMO) On-body system are evaluated and compared to the single-i...
