A novel interference-cancelled home network PLC system based on the binary ZCD-CDMA

Abstract

The transmission channel of Home network PLC (power line communication) are characterized by various noise components and delayed waves generated by load fluctuation and multi-path transmission. In this paper, a novel Interference-cancelled Home Network CDMA-PLC system based on the binary ZCD (zero correlation duration) spreading code are proposed as one solution to overcome the previous problems. The properties of the proposed ZCD-PLC systems are effective for MPI(multi-path interference) and MAI (multiple access interference) cancellation in the CDMA-PLC (code division multiple access-PLC) systems. By BER performance simulation, we certified the availability of proposed ZCD-CDMA-PLC system © Springer-Verlag Berlin Heidelberg 2005.
