| 摘 要： | 文中提出了一种多电平正交振幅调制器(MQAM)的设计与实现方法。该调制器由纠错编码部分、脉冲成形滤波器和混频器构成。实践证明,本设计可在单片FPGA中实现DAVIC协议中所建议的MQAM(M=16,64,256)调制器。该设计可在数字电视机顶盒(STB)内作为实现交互电视(iTV)的主体功能模块,具有较高的实用价值。

| Abstract: | This paper presents a novel implementation method of MQAM modulator. This modulator consists of FEC, FIR filter and DDS synthesizer. Practical application indicates that the implementation complies with the specification given in the DAVIC. It can be used as a main part in iTV module in STB, which implies ifs valuable. |
