Wake-up transceiver protocol for power line communications

Abstract

This paper presents a wake-up transceiver system based on narrowband power line communications (NB-PLC). An energy-pattern based sequence detection algorithm is proposed for the recognition of a wake-up sequence by the receiver. The method is characterized by low computational complexity and does not require channel parameter estimation and adaption. Furthermore, a blind packet repetition technique is introduced that accomplishes periodic impulsive noise avoidance. A realistic and straightforward narrowband power line channel model is presented and the proposed wake-up protocol is verified against it in terms of Monte-Carlo simulations. It is demonstrated, that the method leads to significant improvements compared to state of the art low-complexity PLC systems in typical NB-PLC channels.
