This paper discusses the modeling and analysis of a systematic lossy source channel coding system for errorresilient video transmission. The systematic portion of the transmission consists of a video bitstream transmitted without channel coding over an error-prone channel. Error-resilience is achieved by transmitting a supplementary bitstream generated by Wyner-Ziv encoding of the video signal....

Dual scattering channel (DSC) schemes naturally extend the transmission line matrix (TLM) numerical method beyond the lines set up by P.B. Johns and coworkers. Conceptually, DSC schemes retain from TLM the typical formal splitting of the computed fields into incident and reflected components, interchanged and scattered between adjacent cells, without yet a need for transmission lines. They gene...

Reliable data transmission over lossy communication link is expensive due to overheads for error protection. For signals that have inherent sparse structures, compressive sensing (CS) is applied to facilitate efficient sparse signal transmissions over lossy communication links without data compression or error protection. The natural packet loss in the lossy link is modeled as a random sampling...

We investigate the performance of bends and splitters in graphene nanoribbon waveguides. Although the graphene waveguides are lossy themselves, we show that bends and splitters do not induce any additional loss provided that the nanoribbon width is sub-wavelength. We use transmission line theory to qualitatively interpret the behavior observed in our simulation. Our results pave a promising way...

This paper proposes a method for extending the ability of rotary power flow controller (RPFC) using tap-changer of the RPFC’s transformers. A detailed model of the device is presented to analyze the effects of the tap changer operation on the performance of the RPFC. To evaluate the results, the RPFC model is simulated using PSCAD/EMTDC software. Dynamic operation of the RPFC on a 400 kV transm...

A line driver with configurable pre-emphasis is implemented in a 65 nm CMOS process. The utilizes three-tap feed-forward equalization (FFE) architecture. relative delays between the taps are selectable increments of 1/16th unit interval (UI) via an 8-stage delay-locked loop (DLL) and digital interpolator. It also possible to control output amplitude source impedance for each tap programmable ar...

In this paper, a miniaturized coplanar waveguide fed (CPW-fed) tapered slot antenna (TSA) is introduced for breast cancer detection. Here, a modified CPW to slot-line transition structure with an air-bridge is employed to broaden the transition bandwidth and increase the radiation efficiency. Through these applied modifications, negative features of the original TSA (limitation of transition) a...

In this paper, Intelligent water drop algorithm (IWD) is used to analyze single overhead line connected to grid-grounded arrester. In this approach, at first Norton’s equivalent circuit of the overhead line over lossy soil is computed by method of moments (MoM) and then for the problem under consideration, a nonlinear equivalent circuit in the frequency domain is proposed. Finally applying inte...
