A high performance baseband transceiver for in-vehicle power line communications

In-vehicle power line communication (PLC) provides a solution for high data communication in the automotive networks without increasing volume, weight and cost of the wiring harnesses. This paper presents the vehicle power line channel model. Also, we propose the design of baseband transceiver, which specifically aimed at this channel model. In transmitter part, the corresponding preamble structure is designed. In the receiver part, it contains packet detection, symbol timing synchronization, sampling clock offset synchronization, channel estimation/equalization, and the nonlinear blanking process for reducing the impulsive noise. Functional simulations show the validity of these algorithms and system performance of the proposed transceiver.
