The power-line communications channel (PLC) is one of the harsh and challenging channels due to heavy load and noise impairments. Sending and/or receiving of data bits over the PLC channel can be easily affected; therefore, several investigations have been conducted to illustrate interference effects over PLC where intermittent noise plays a major role in this type of communications channel. The in-building...
The fluorescent lamps or fluorescent tubes are low pressure mercury-vapor gas-discharge lamps that use fluorescence to produce visible light. These lamps inject noise into the power-line communications channel. This can have a detrimental effect on the power-line communication system. In this paper we investigate the effects when the fluorescent lamps with electronic ballasts are seen as noise sources...
To realize the auto operation of the remote recharge process of IP telephone and the low-balance add-fund notice of IP account, an IP telephone remote auto-recharge system based on multiagent is developed by the author.
