    • A digital broadcasting transmission and/or reception system having an improved reception performance and a signal-processing method thereof. A digital broadcasting transmitter comprises a randomizer to input and randomize data streams including a plurality of segments having at least one segment having one or more null packets, a null packet exchanger to create known data having a predetermined pattern and to replace the null packets at positions of the segments having the null packets of the randomized data streams to insert the known ‘data, an encoder to encode the data streams to which the known data is inserted, and a modulation/RF unit to modulate, RF-modulate, and transmit the encoded data streams. A digital broadcasting receiver detects the known data’ from a signal received from the digital broadcasting transmitter and uses the detected known data for synchronization and equalization, so that a digital broadcasting reception performance of the digital broadcasting receiver can be improved at poor multipath channels.
    • 一种具有改善的接收性能的数字广播发射和/或接收系统及其信号处理方法。 数字广播发射机包括随机化器,用于输入和随机化包括具有至少一个具有一个或多个空分组的分段的多个分段的数据流;零分组交换机,用于创建具有预定模式的已知数据,并在位置 具有随机化数据流的空分组的段插入已知的数据,编码器对已知数据插入的数据流进行编码,以及调制/ RF单元来调制,RF调制和发送 编码数据流。 数字广播接收机根据从数字广播发射机接收的信号检测已知数据,并使用检测到的已知数据进行同步和均衡,从而可以在恶劣的多径信道下改善数字广播接收机的数字广播接收性能。
