A Low Complexity 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. In this paper, a high data rate OFDM baseband receiver for in-vehicle PLC is presented. Suffered harsh multipath vehicle power line effect, impulse noise and 25 p. p. m. sampling clock offset (SCO), the whole receiver is proposed to recover the signal with less-complexity-based design. Functional simulation shows system performance of the proposed receiver, and the logic design, for circuit implementation, of each function block are also presented. The required gate-count is around 595k under TSMC 90 nm technology, and complexity has 9.77 % saved-ratio comparing with direct implementation.
