Abstract: The power line communication is used for transferring data over low voltage power line, where electrical power is transmitted over high voltage transmission line distributed over medium voltage & used inside the building at lower voltages. This technology can be extensively used in centralized electric meter reading, remote monitoring of electrical equipment, building automation and security control, stage lighting and street lighting control applications, information displays To overcome the electromagnetic strong polluted channel a direct sequence spread spectrum concept s used with its inherent processing gain.To achieve a simple design to adapt the spectrum to the channel by chip-shaping and use sub optimum detection scheme to avoid synchronization loops.
