Abstract

Frame structure, modulation and transmission of CMMB are analyzed in this paper, a baseband receiver solution is proposed in paper, including synchronization, channel estimation and FEC. In this solution, synchronization signal correlation is adopted to realize the synchronization, channel estimation uses one-dimension linear interpolation, and LDPC decoder is realized by layered decoder algorithm. This solution not only reduces the system complexity, but also achieves well performance in severe environment.
