adaptive coder造句
例句與造句
- The approach in this thesis first design the best performance channel code in different channels and different snr , then design the adaptive coder / decoder . the receiver continually estimates the fading and noise of the channel and transmits them to the transmitter by reverse channel . then the transmitter use these information to choose the best channel code adaptive the current channel
本文提出的自適應(yīng)調(diào)制方案首先設(shè)計(jì)各種信道衰落和信噪比條件下的最優(yōu)信道編碼，再設(shè)計(jì)一種能夠完成這些信道編碼解碼的自適應(yīng)編碼解碼器；接收機(jī)不斷估計(jì)信道的衰落程度和噪聲功率，并通過(guò)反向信道反饋給發(fā)射機(jī)；發(fā)射機(jī)據(jù)此選用最適合當(dāng)前信道的信道編碼，實(shí)現(xiàn)自適應(yīng)。 - This paper first research on main technologies used by avs standard , which include prediction , transform , quantization , in - loop filter , and entropy encoding , and then focus on the 2d - vlc entropy coder of avs , which is context - based adaptive coder . this encoder operates on run - level pair , and it uses the type of current block and value of current coefficients to switch vlc code - table . these tables are designed according to the distribution of transformed coefficients , and this way is much better than using only one table to code all residual coefficients in one 8x8 block
本文首先詳細(xì)研究了avs標(biāo)準(zhǔn)的核心技術(shù),包括預(yù)測(cè)編碼、變換量化、環(huán)路濾波器以及掃描和熵編碼等,之后重點(diǎn)研究了avs標(biāo)準(zhǔn)中使用的基于上下文的2d - vlc變長(zhǎng)編碼方法,這種方法編碼的是( run , level )數(shù)對(duì),同時(shí)根據(jù)當(dāng)前編碼塊的類(lèi)型和殘差系數(shù)這兩種上下文信息來(lái)切換碼表,這些碼表是預(yù)先根據(jù)變換系數(shù)在不同位置的分布信息設(shè)計(jì)好的,這樣要比只使用一個(gè)變長(zhǎng)碼表來(lái)編碼塊內(nèi)所有位置上的殘差系數(shù)的壓縮效果要好得多。 - It's difficult to find adaptive coder in a sentence. 用adaptive coder造句挺難的
