threshold decoding-
Low power design methods of setting threshold on viterbi decoder
譯碼器設置門限的低功耗設計方法After a great amount of detailed computer simulations and concise qualitative and quantitative theoretical analysis, the turbo codes " parameters and fpga specific hardware implementation architecture suitable for being integrated into dtv systems are determined. furthermore, the codec is completely designed with verilog hdl, ending with an occupation of less than a 600 - thousand - gate fpga chip. at this lowest hardware cost, a white noise snr threshold of 1. 8db at a net stream rate of 6mbps is achieved, which exceeds all other existent dtv systems " performance
經過大量詳細的計算機軟體模擬和簡明扼要的定性與定量的理論分析，最終確定了數字電視系統中適合採用的turbo碼參數及針對fpga特殊構架的硬體實現結構，並用verilog硬體描述語言完成了turbo碼編譯碼器的完整設計，以佔用不到一片60萬門fpga晶元的較少的硬體資源取得了在6mbps凈碼率下1 . 8db的白噪聲信噪比門限這一遠遠超過現有任何數字電視系統的性能。
