摘要
首先简要介绍了DTMB数字电视标准,再着重分析了DTMB数字电视解调系统的硬件组成和软件设计方法,对信道解调芯片ATBM8878的内部框图、工作原理和外围电路连接都进行了细致的分析,并较为详细地介绍了软件实现的流程。最后总结了DTMB接收系统的性能测试方法,并提供了实验室的性能测试结果,证明该DTMB解调系统的设计是可行的。
Firstly, the standard of DTMB is discussed briefly. Then the hardware structure and software design of the demodulation system are analyzed, and the internal diagram, operation principle and peripheral circuit connection of the digital channel demodulation chip ATBM8878, and the software work flow are focused on. Finally, the performance testing methods of DTMB receiving system are summarized and the test report in laboratory which can prove that the design of DTMB demodulation system is provided.
