  1. The ionosphere is a complex medium, which is aeolotropy, asymmetry, dispersive and changes randomly with time. in order to improve the communication quality of the shortwave that depends on the ionosphere, we should have aknowledge of the current condition of the ionosphere in real time. the backscatter sounding of high frequency can diagnose the real - time channel characters for shortwave communication or hf radar, which is great assistant to shortwave communication and hf radar

    電離層是隨機時變，各向異性，非均勻、色散的復雜介質。為了保證依賴于電離層進行的短波通信質量，必須了解電離層的實時狀態信息。高頻返回散射探測可以實時監測與短波通信或高頻天波雷達相關的天波傳播通道的狀態，對短波通信和天波雷達工作起了重要的輔助作用。
  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-判決反饋聯合均衡系統結構，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離散正則模型概念，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；基於離散正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子空間盲辨識演算法；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；提出了基於離散正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. After the system has been synchronized, we first use the least square method to make channel estimation, then separate the channel response information from the channel noises by dft. a weighting function based on the minimum mean square error ( mmse ) criteria can be applied to the time domain channel impulse response

    在系統同步條件下，首先使用最小平方方法來估計通道響應，然後利用離散傅利葉變換的性質把通道響應信息和通道噪聲分離，並在時域按最小均方誤差準則做加權處理。
  4. This paper studies target detection algorithms using polarimetric one - dimension range profile. at first by exploiting polarimetric information in different polarization channels, a fused and enhanced one - dimension range profile is obtained by pwf. then we can detect radar target through integration of scatters in different resolution cells or the number of detected scattering points

    首先利用不同極化通道的相關性信息，將各個極化通道的一維距離像通過極化白化濾波（ pwf ） ，抑制相關雜波，提高信雜比，融合得到一幅改善了的一維距離像，然後通過多個散射中心的能量徑向積累判定目標的有無。
