| Summary: | 碩士 === 國立臺灣大學 === 電子工程學研究所 === 92 === In the thesis, we propose a DVB-T（Digital Video Broadcast - Terrestrial）baseband receiver. The architecture is established according to the standard and several channel impairments. The receiver architecture has three major parts including synchronization, channel response estimation and channel decoding. The synchronization part comprises symbol boundary detection and carrier frequency offset and timing offset estimation and tracking. Channel response is estimated by means of two-dimension interpolation of scattered pilots. In the channel decoder part, a concatenated error correction decoder is used. The outer decoder is Reed-Solomon decoder and the inner decoder is a hard-decision Viterbi decoder. In the thesis, several simulations and performances are presented and discussed in the final.
