  1. The one - dimension effective fpk equation of colored noise serves as our starting point to evaluate the effect of noise color on communication system design. the theory of ber versus input snr per bit is developed and a new procedure to determine the system parameters that influence the minimum ber is proposed. it is shown that the communication system ' s performance is related to the turnable system parameters as well as the noise correlation time

    在指數相關高期色噪聲情況下，本文以一維有效色噪聲fpk方程作為研究的出發點，理論分析了限帶高斯色噪聲通道中脈沖幅值調制數字信號傳輸的誤碼性能，給出了非線性接收器的接收性能曲線，充分體現了噪聲相關時間的影響。
  2. The study has not received adequate attention as far as media coverage is concerned. publicity would be beneficial to arouse public awareness

  3. It is shown by structural seismic response of four wavelets that littlewood - paley wavelet is not suitable for structural seismic response, because structural response is too small, meyer wavelet is a better wavelet for structural seismic response, for it ' s structural response is agreement with the finite element method, and also harmonic wavelet, structural response under earthquake is a little bigger than finite element method, structural response under odd exponent wavelet is also bigger than finite element method, this method is very simple by wavelet transform, wavelet transform method is different from old methods, one is with which not only knows the effects of earthquake wave detail frequency - band on structural response, but also considers earthquake wave ' s non - stationary of frequency and time - domain value, another is the second mode shape and higher mode shape response that do n ' t attenuate so fast

    通過對這四種小波的結構地震反應分析研究說明： littlewood ? paley小波不適合於用來作結構地震反應分析，因為在littlewood ? paley小波下的結構地震反應太小，不符合實際情況；用meyer小波作結構地震反應分析比較合適，和有限元法的結果比較接近；也可以用諧波小波來作結構地震反應分析，只是在諧波小波下的結果略為偏大；單邊指數小波下的結構地震反應分析比有限元法稍大一點，它通過小波變換大大簡化了結構地震反應分析。用小波變換方法來進行結構地震反應分析和以往方法不同的是：它不僅可以知道地震波的具體頻率段對結構反應的影響，而且同時考慮了地震波的幅值非平穩性以及頻率非平穩性；另外與以前方法得到的結果有差異的是，第二振型及以後的高一點的振型的反應沒有以前的方法衰減得快。
  4. The algorithm have the good one - way property, high sensitivity to initial values and good security due to the intrinsic characteristic of chaotic system and rijndael algorithm. the simulation experiment demonstrates the convenience and good hash performance ; 3 ) a new scheme of digital voice secure communication was proposed based on chaotic modulation without additional synchronization. the modulation sequence generated by chaotic logical mapping was used to encrypt the digital voice signal

    混沌系統和rijndael演算法的固有特點使該演算法具有較好的安全性、對初值有高度的敏感性以及較好的單向性能，並且易於實現，是一種有效的單向hash函數； 3 ）研究了一種無需同步的基於混沌調制的數字語音保密通信系統的方案，利用邏輯映射產生混沌調制序列，以該序列作為密碼對數字語音進行加密處理，為了更好的隱匿信號特徵，混沌調制在小波分解的基礎上，對不同的通道使用不同的參數進行，並借鑒混沌掩蓋對信息信號進行了限幅處理，使密文完全隨機化。
  5. While designing hardware and software, some methods are used to decrease the noise such as power shielded, signal value limited and alarm, etc. the test of the system showed that the performance and technical parameters are eligible as expected

    在硬體和軟體的設計上，採取了多種抗干擾措施。如電源屏蔽、限幅、通道隔離、數字濾波、越限報警等，確保控制系統的安全可靠運行。
  6. Over - the - horizon radar ’ s beam - frequency is high frequency band and its wavelength is so long that the annate ’ s characters are very complicated when applicated on the ship. the character of coupling between cells and the environment must be measured to compensate in the radar signal process step. the ship - based over - the - horizon radar uses cfa ( crossed field antenna ) as array antennas ’ cell
