We derive the capacity of the state-dependent half-duplex relay channel without source-destination link. The output of the state-dependent half-duplex relay channel depends on the randomly varying channel states of the source-relay and relay-destination links, which are known causally at all three nodes. For this channel, we prove a converse and show the achievability of the capacity based on a...

In this article, we study a dual-hop mixed power line communication and radio-frequency (PLC/RF) system, where the connection between PLC link RF is made by decode-and-forward or amplify-and-forward relay. It assumed that channel affected both additive background noise Poisson–Gaussian impulsive which suffer from log-normal fading, while undergoes generalized Rician fading. Based on model, anal...

Using the worldwide already existing power lines as a communication medium for local area networking (LAN) has received much interest for many indoor information sharing applications. However, the indoor power line communication (PLC) channels demonstrate hostile characteristics for broadband signal transmission. A lot of efforts have been made in order to apply some advanced technologies, whic...

Automation means Delegation of human control to machine. A PLC (Programmable Logic Controller) is a device that was invented to replace the necessary sequential relay circuits for machine control. A SCADA (Supervisory Control & Data Acquisition System) is used to control the process where person cannot go or stay for longer period. The aim of tis paper is to provide information about hoelectric...
