一种多媒体广播无线信号鲁棒传输方法
摘要：
本发明公开了一种多媒体广播无线信号鲁棒传输方法。在发明的多媒体广播无线信号鲁棒传输方法中，多媒体广播无线信号在多媒体广播无线发射机端多媒体数据流经媒体数据处理、比特流经BCH编码、比特交织、LDPC编码、码元调制、星座旋转、码元交织、帧体形成、时域训练序列插入成帧、脉冲成形、上变频至载波上形成射频信号发射到空中无线信道并由接收机端接收处理多媒体广播无线发射机端所发送的信号。该多媒体广播无线信号鲁棒传输方法具有接收同步时间短、高传输效率、可控多业务等优点。
摘要（英）：

The invention discloses a robust transmission method of multimedia broadcasting wireless signals. In the robust transmission method of multimedia broadcasting wireless signals of the invention, through the steps of multimedia data stream processing by media data, BCH encoding of the bit stream, bit interleaving, LDPC coding, code element modulation, constellation rotation, code element interleaving, frame body formation, time domain training sequence insertion frame formation, pulse formation and up frequency conversion to wave carriers, multimedia broadcasting wireless signals are formed into radio frequency signals at the multimedia broadcasting wireless emitting machine ends to be sent to aerial wireless signal channels, and signals sent by the multimedia broadcasting wireless emitting machine ends are received and processed by the receiving machine ends. The robust transmission method of multimedia broadcasting wireless signals has the advantages of short receiving synchronizing time, high transmission efficiency, controllable multi-service and the like.
