1、同濟(jì)大學(xué)電子與信息工程學(xué)院博士學(xué)位論文DVB-C基帶芯片的設(shè)計(jì)與實(shí)現(xiàn)姓名：史曉鋒申請(qǐng)學(xué)位級(jí)別：博士專業(yè)：控制理論與控制工程指導(dǎo)教師：陳詠恩20070301摘要4，簡(jiǎn)單回顧基于隨機(jī)梯度迭代的盲均衡算法，重點(diǎn)討論獨(dú)立于載波的常模數(shù)算法。從均衡器是否包含反饋以及反饋的方式、采用直接型或者倒置型濾波器結(jié)構(gòu)、采用符號(hào)間隔還是分?jǐn)?shù)間隔這三個(gè)方面，分析不同結(jié)構(gòu)均衡器的特點(diǎn)。給出采用不同算法和結(jié)構(gòu)均衡器的性能仿真結(jié)果。5，研究在混合信號(hào)電路(AGC和ADC)設(shè)計(jì)過程中面臨的主要問題和解決方法。提出芯片中固定系數(shù)FIR濾波器和均衡器等關(guān)鍵模塊的優(yōu)化實(shí)現(xiàn)方案。設(shè)計(jì)結(jié)果表明這
2、些優(yōu)化保證了解調(diào)器的整體性能指標(biāo)。6，研究基于SystemC的定點(diǎn)仿真技術(shù)和基于參考模型的功能驗(yàn)證，提出時(shí)序精度層次的參考模型。對(duì)基于FPGA的原型驗(yàn)證系統(tǒng)的組成、流程和一些基本驗(yàn)證準(zhǔn)則進(jìn)行了討論。以DVB．C基帶芯片為實(shí)例，針對(duì)基帶芯片驗(yàn)證中的難點(diǎn)提出相應(yīng)策略。關(guān)鍵詞：正交幅度調(diào)制、時(shí)鐘同步、插值、載波同步、自適應(yīng)均衡、混合信號(hào)、SystemC參考模型、FPGA驗(yàn)證nAbstractDVB—ChasbeenthenationalstandardofdilgitalCableTVinourcountry．WithsteppingintoHDTVe豫fro
