摘要: 在本論文裡, 我們針對可能影響電視而產生鬼影的原因, 研讀了現有有關 NTSC和HDTV兩種系統之多重路徑通道等化與時序載波回復的演算法, 並以 此為基礎做進一步的改進, 最後將整個系統整合做電腦模擬,至於硬體部 份, 針對等化器及計算其係數部份作電路設計, 並利用 Verilog 模擬其 正確性. In this thesis, we study the existing algorithms for multipath equalization, timing and carrier recoveries. Then we propose improved algorithms for these demodulation problems, which have lower hardware complexities and better stability than the existing algorithmns generally. Computer simulations of the total demodulation systems show satisfactory performances. As for hardware realizations, structures for the filter block and its corresponding coefficient update block of the multipath equalizer are designed and Verilog simulated.
