This scheme can switch transmit packets of different lengths by means of its capability for channel estimation; longer packets will be employed in better channel condition. Experimental results obtained from 3 typical PLC channel models (CM2, CM3, CM4) indicate that the proposed adaptive packet switching scheme achieves varying degrees of improvements for transmission performances and the result of channel model 3 is among the best.
