bandwidth reduction 中文意思是什麼
bandwidth reduction
解釋
帶寬壓縮-
The principal advantage over the dual filter coherent detection is a four - fold reduction in bandwidth
與雙濾波器相干檢波相比的主要優點是帶寬減少了四分之三 -
A patch antenna with etched holes on the ground plane is also studied. the performance of the antenna at the resonant frequency is analyzed by using the fdtd method together with the pml boundary treatment. the results show that the surface waves are suppressed greatly, the bandwidth is improved and a 1 odb reduction on the sidelobe level is achieved at the 110 and 260 directions in the e plane
全面地研究了地面腐蝕周期圓孔結構的電磁晶體貼片天線在基波頻率處的性能，用fdtd方法並結合pml邊界處理技術對該天線所取得的研究結果顯示，本文設計的地面腐蝕型電磁晶體結構抑制了貼片天線中的表面波，增加了天線的帶寬，並有效地削弱了旁瓣，使天線的e面方向圖上110和260方向的兩個旁瓣被削弱了10db 。 -
Multiband transmission permits a reduction in error probability in exchange for at least a twofold increase in bandwidth and carrier power
多頻帶寬傳輸能降低誤差概率，但其代價是速度及載波功率至少增加一倍 -
Experiment results also show that our improved algorithm achieves the same perceptual quality as g. 726 standard while our improved algorithm uses a lower bit rate. therefore, our proposal may lead to telecommunication bandwidth saving and storage requirement reduction
經實驗結果驗證，本語音編碼演算法與g . 726語音波形編碼標準相比，比特率下降了15 . 19 %以上，同時兩者的語音質量完全沒有差別。 -
The compression over text is a relatively small 2 : 1, but this is still a significant reduction in bandwidth requirements
對文本的壓縮相對較小，為2 : 1 ，但仍然大大降低了帶寬需求。 -
Stsc does not only reduction statistical performance of multi - hops paths but also decrease estimation of upper bound of traffic delay and tail distribution. we also present generalized integrated service model ( cis model ) that founds bandwidth brokers in autonomous systems ( as ) that support traffic aggregating and traffic tagging. thus as are able to work under hybrid mode, so cis model is more adaptive to integrated data communication in broad bandwidth ip network
本文還提出了廣義集成服務模型，通過在支持通信量聚合和標記的自治域中設定帶寬代理和在網路邊界實施面向應用通信量特徵的分類機制，使得自治域能夠在混合模式下工作，從而能更好地適用於寬帶ip網路中的綜合數據通信。
