摘要: | In this paper, an OFDM baseband receiver for DVB-T/H is presented. The receiver contains four synchronizations, an OFDM symbol synchronization, a carrier synchronization, a sampling clock synchronization and a scattered pilots synchronization. This paper proposes several novel designs to reduce the synchronization latency and hardware complexity. The carrier and clock synchronization loops are fully digitalized schemes. The scattered pilots synchronization adopts a two stages scheme to reduce the detection latency. In addition, the pre-filling scheme reduces the latency of channel estimation. The design result shows that the equivalent gate count is about 810K gates including 102.8KB memory(1). |
