摘要

In a Non-Data-Aided (NDA) broadcasting system such as DVB-T/H, blind transmission mode, guard interval (GI) length detection and coarse symbol synchronization (CSS) play important roles to estimate the transmitted OFDM symbol parameters and start the synchronization processes. In this paper, a single hardware and division-free architecture, modified from Normalized-Maximum-Correlation (NMC) architecture, for DVB-T/H blind mode/GI detection and coarse symbol synchronization (CSS) is proposed. By adopting the proposed twister memory access scheme and sequential blind mode detection scheme, the architecture reduces 33% of memory costs and at most 58.18% mode detection latencies.
