Adaptive CPFSK Modulation for Power Line Communications

Abstract

Power-line communication (PLC) has an advantage of no additional wiring for communications, but it may not be suitable for high speed signal transmission due to the nature of power-line. In this paper we consider the use of adaptive CPFSK modulation scheme robust to harsh power-line channel condition. The modulation parameters are initialized and adjusted during the data transmission without interrupt. The performance of the proposed scheme is analyzed and verified by computer simulation.
