In addition, the beamforming techniques for cdma systems are discussed emphatically. the algorithm based on code filtering is deduced in detail theoretically, and the performances such as convergence and bit error rate ( ber ) are simulated. meanwhile, we improve a decision - projected algorithm based on least - mean - square ( lms ) error
論文重點討論了cdma系統的波束形成技術,在理論上詳盡地推導了基於擴頻碼濾波的波束形成演算法,對其收斂性、誤碼率等進行了計算機模擬;針對基於最小均方( lms )誤差的一種判決映射演算法進行了改進。The main work is as follows : 1. an error resilient algorithm to collaborate multiple description coding ( mdc ) and error concealment ( ecn ) is presented. the strategy of this method is to reconstruct the low quality image followed by recovering the lost wavelet tree with error concealment method when end - user receives few descriptions
在誤碼環境下,要保證解碼端重構圖象的質量,就要綜合採用多種抗誤碼方法,本文對差錯復原技術的綜合應用進行了研究,具體內容如下: 1 、提出了圖象多描述編碼與差錯隱藏相結合的差錯復原演算法,在接收端接收到的描述較少時,首先根據接收到的若干描述重構低質量的圖象,然後採用差錯隱藏方法恢復丟失的子波樹。Prediction algorithm is a most simple one of all methods on images compression. and it explore directly the spectral correlations of hyperspectral images. its method is very simple and easy to be implemented. prediction takes full advantage of the spectral correlations to use transmitted spectral to predict current spectral, then predictive error that original spectral is substracted by predictive spectral is coded. the predictive error is wiped off the spectral correlations, so compression is easier than before
預測技術是最簡單的一種方法,它直接探索譜帶與譜帶之間的相關性,具有演算法簡單、易於實現的特點。預測技術充分利用圖像的相關性,用已傳輸的值對當前值進行預測,然後對預測值與真實值的差即預測誤差進行編碼處理。預測產生的殘余誤差已被去相關,因而比較容易壓縮。Meanwhile, the telephone gateway in tetra system is introduced. in further research, the principle of tetra speech coding algorithm ? algebraic codebook excitation linear prediction ( acelp ) is introduced and analysed in detail, which is a advanced codebook excitation linear prediction ( celp ). acelp algorithm replaces the excitation signals with algebraic codebook and uses some technique such as minimizing the mean square error ( mse ) and the analysis - synthesis method to obtain characteristic parameters of speech
同時,介紹tetra系統的市話網關,並在接下來的研究中詳細介紹tetra電話網關中應用到的語音編解碼演算法? ?代數碼本激勵線性預測碼( acelp )的基本原理,它是一種簡化了的碼本激勵線性預測碼( celp ) ,它把激勵信號用代數碼本代替,並且運用了均方誤差最小、分析?合成等技術提取出語音的特徵參數,極大地降低了比特率,而且具有較好的重建語音質量。分享友人
