precoding 中文意思是什麼

precoding 解釋
預編碼
  1. By precoding we mean all methods applied at the transmitter that facilitate detection at the receiver. at first, we investigate the application of precoding in the mimo system and put emphasis on the discussion of tomlinson - harashima

    由模擬結果可知，在採用比特和功率分配演算法以後，當ber = 10 - 3時，系統將獲得至少5db的性能增益。
  2. Then this paper makes some overview and simulation on the application of three precoding algorithms under the flat fading channel, which are linear preequalization, tomlinson - harashima precoding ( thp ) and lattice reduction - aided ( lll ) vector precoding

    本文對三種常見的預編碼演算法在平坦衰落通道下的應用進行了綜述和模擬研究，包括迫零線性預均衡、 thp預編碼和格約簡輔助矢量預編碼等演算法。
  3. The method does not need precoding or constant - modulus ( cm ) modulating

    該演算法無需預編碼或恆模調制。
  4. Some theories and key techniques about mimo have been focused worldwide, including the research on mimo detection and precoding techniques

    與mimo無線通信相關的理論和關鍵技術也成為國內外研究關注的焦點，其中包括對mimo檢測技術和預編碼技術的研究。
  5. Mimo precoding can reduce the receiver ’ s complexity, specially suited for the downlink of the cellular mobile communication system, so it has been noticed by the worldwide researchers these years

    Mimo預編碼技術可以大大降低接收機的復雜度，特別適合於蜂窩移動通信系統的下行鏈路，因此在最近幾年受到了國內外研究人員的廣泛關注。
  6. The simulation results prove that among the three precoding algorithms, lll precoding strategy demonstrates the best ber performance. and the simulation results also tell us if lll precoding algorithm is combined with the v - blast detection, the performance of the precoding system will be improved by the v - blast lll precoding strategy

    與v - blast演算法相結合的格約簡輔助矢量預編碼演算法由於在v - blast中根據當前通道狀態特徵，在預編碼時對信號進行重新排序，因此提高了預編碼性能。
