Abstract
We design a power line communication (PLC)
modem robust to frequency-selective and timevarying
channel condition. We consider the use
of an adaptive CPFSK modulation scheme at a
transmission rate of up to 2Mbps and TDMA
scheme for multiple access. We propose a
synchronization scheme for robust and fast frame
synchronization and the channel change detector
for adaptive modulation. The performance of the
designed modem is verified by computer
simulation. Numerical results show that the use
of the proposed modem can transmit data without
interruption even in the case of sudden change of
the channel condition.
