摘　　要：在地面数字电视基站建设中,为了满足覆盖区域多套标清和高清节目的传播要求,常常需要配置多台数字电视激励器。为了简化基站设施建设,提高硬件复用,提出了一种多通道数字电视调制器解决方案,实现仅用一台激励器即可完成基站建设。以五通道DTMB调制器为例完成了在FPGA芯片上的实现。经过实际测试满足设计要求,具有较大的实用价值。In the construction of digital terrestrial TV broadcasting station, more than a couple of digital TV modulators are needed to meet the demands of broadcasting multiple SD and HD programs of coverage area. To simplify the construction of station and multiplex the hardware, this paper provides a solution of multi-channel digital TV modulator. Only one exciter is needed to fulfill the construction of the station. A five channel digital TV modulator is implemented on the FPGA as an example. The solution meets the design requirements by testing and has great practical value.
