achievable rate 中文意思是什麼

achievable rate 解釋
可達速率
  • achievable : adj. 做得成的,可完成的。
  • rate : n 1 比率,率;速度,進度;程度;(鐘的快慢)差率。2 價格;行市,行情;估價,評價;費,費用,運費...
  1. Unfortunately, in these situations, the notorious blocking artifacts resulting from block dct set a severe limit on the achievable bit - rate with acceptable quality

    然而,基於dct的傳統視頻壓縮方法由於在低比特率下出現塊失真嚴重影響恢復視頻質量。
  2. ( b, sensitive and accurate : subhealthy district position quantization measures the rate of accuracy and more than 90. 6 %, even if there are three, five cells of the pathological change, can measure out immediately too, this is a traditional detecting instrument far not achievable level

    靈敏準確:亞健康區部位量化檢測準確率達90 . 6 %以上,即使病變的細胞只有三、五個,也可即時檢測出來,這是傳統檢測儀器遠遠不能達到的水平。
  3. Based on these advantages we analyze the performance of constant - power variable - rate m - qam schemes for spectrally efficient data transmission over nmf channels. by introducing the adaptive modulation approach, we gain two things : 1 ) the error rate is kept at a constant level. 2 ) the achievable spectral efficiency comes within 5 db of the shannon capacity limit. at the last chapter, the presentation of a single base station and a single mobile scenario proved the feasibility of adaptive schemes

    然後作者的精力轉入通道的自適應方案的研究中,首先通過研究發現nakagami衰落因子的適當調整可以近似於常見的瑞利衰落和萊斯衰落,接著研究在無線通道中採用三種不同自適應方案時的通道容量,研究表明速率的調整是增加通道容量的關鍵,在此基礎上,著重研究了離散變速率qam的情況,表明這種調制方案無論在頻帶利用率還是在系統平均誤碼率比其它情況提高很多。
