  1. Another advantage, contrast to using convolutional codes or turbo codes, is its low complexity while maintain high ber performance because the check equations are used to terminate the both iterations. we develop the theoretical error free feedback bound for bpcm - id and predict the threshold for decder convergence using the extrinsic information ransfer chart ( exit )

    利用非則ldpc具有不同度的信息節點概率密度演化的差異,對高階星座中具有較高級別的通道提供額外的保護,可使迭代判決時,星座集擁有最大的無錯歐氏距調和均值,從而改善系統的迭代收斂特性。
  2. Firstly, a new joint filterbank precoders and decision feedback equalizers structure is proposed, and the corresponding optimization result based on the maximal mutual information criterion is derived. secondly, the concept of dt canonical model is proposed, which is very suitable for the task of blind signal processing based on the second - order statistical of the observations. thirdly, the methods of blind equalization and identification of the tv dispersive channels are researched systematically based on the proposed dt canonical model, and a subspace blind identification algorithm of the time - invariant channel matrix is developed

    本文創新性的成果在於:提出了預編碼-判決聯合均衡系統結構,並從理論推導得出了對應的最大互信息量最優化設計結果;首次提出了時變色散通道的則模型概念,該模型適宜於利用觀察數據的二階統計量進行盲信號處理;基於則模型對時變色散通道進行了系統的盲均衡和盲辨識方法研究,提出了對時不變通道矩陣的空間盲辨識演算法;針對誤差傳播效應問題,提出了可以消除誤差傳播效應的兩級盲辨識演算法;提出了基於則模型的直接盲均衡演算法;提出了基於特徵恢復思想的神經網路直接自適應盲均衡演算法。
  3. Secondly, we define a discrete lyapunov functional for the dde with local positive or negative feedback in the delay term, and give a proof of the validate of this definition and some basis properties of this functional. furthermore, we deduced some sufficient conditions that guarantees not only the existence of the global attractor and some properties of limits set, but also the morse decompositions of the global attractor. in particular, we study the properties of the solutions of the dde with local monotone in the delay term

    其次,本文對于時滯項滿足局部或者局部負條件的時滯微分方程,定義了散lyapunov泛函,並證明了這樣定義的合理性及其有關性質,給出了全局吸引存在的一些充分條件,利用這樣定義的lyapunov泛函證明了全局吸引具有morse分解的結構以及極限集的若干性質,同時,利用極限集的性質證明了在一定條件下,時滯項局部單調系統解的性質。
