DTMB接收机本地训练序列的简化

Simplification of Local Training Sequence in Digital Television Multimedia Broadcasting Receiver

介绍了数字电视地面广播(DTMB)系统帧结构的3种模式,并通过相同模式下的序列简化和序列长度的统一,对本地训练序列进行了简化。仿真结果表明,简化后的序列性能良好。

In this paper, three frame structure modes in Digital Television Multimedia Broadcasting（DTMB） national standard （GB 20600-2006） are introduced. And then, by using the sequence simplification in the same mode, and the unification of sequence length, the local training sequences are simplified. The simulation results prove the good performance of the simplified sequence.
