Adaptive CPFSK modulation for power line communications

Abstract

Power-line communication (PLC) has an advantage that it can use existing facilities for communication, but it may not be suitable for wide-band signal transmission due to the nature of the 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 by using line probing technique. The performance of the proposed scheme is analyzed and verified by computer simulation.
