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.
