The new method is a modified pts method, and can make good compromise between performance and computational complexity. the dissertation explores, by means of computer simulation, how the conventional method based on amplitude - limiting and filtering affects the performances of wavelet packet modulation signals, and presents a new method, namely, selective mapping / amplitude limiting / filtering method, which proves to be effective, simple, and have better ber performance
並基於自子波變換和時間、尺度解析度的概念，從理論和模擬實驗兩方面對通道建模和時間/尺度rake接收機進行了分析，並與傳統的kake接收機進行了比較，結果表明時間/尺度聯合分集能有效地克服高速衰落多徑通道的影響。 -

This paper goes on with analysis of the phased array radar calibration theory and compare of different schemes, then the best is adopted. 2 mhz digital circuit mainly composed of dds ( direct digital synthesis ) chip, which carries out the shift of the phase and the limit of the amplitude, has been designed and debugged successfully. it is used to substitute for the conventional phased shift circuit and amplitude limiting circuit which work at the radio frequency, so the all - digital transmit channel of phased shift array radar is achieved
本論文研究的重點是：針對傳統相控陣雷達系統收發（ t r ）組件中的移相和限幅功能均在射頻段完成，大膽利用直接數字合成（ dds ）晶元組成頻率在2mhz左右的數字電路代替傳統相控陣雷達在射頻段進行移相和限幅的電路，從而組成全數字發射通道，使對相位和幅度的控制和調試更方便快捷，並設計具體的電路驗證此方案的可行性。 -
The authors collected the spectral data of wheat in different occasion, got rid of the noises which happened in the course of measuration by ways of averaging near spectral data and ways of setting limiting figure to amplitude, then the most important characteristic points were gained
然後根據實測的3個不同時期小麥的反射率曲線，在進行了均值去噪處理之後，設定振幅閥值，排除了殘余噪音干擾，從而提取了曲線最重要的特徵點。 -
The paper researches on the control of chaos or hyperchaos via the method of the tune - delayed feedback control ( dfc ), the proportional periodic pulse perturbation to the system variables ( pp - sv ) and limiting amplitude
本文主要對時間延遲反饋法（ dfc ） 、正比于系統變量的周期脈沖擾動法（ pp - sv ）及限幅法這三種控制混沌和超混沌系統的方法展開了研究工作。 -
The frequency difference sensitivity of the modulation mode and the ability to overcome distortion by limiting amplitude of the signal and to overcome interference also affect the performance, too. in this paper, the relationship between the ability to overcome interference and the modulation mode is discussed at first. then the characters in some aspects specif ' ed above of some common modulation mode such as mfsk mpsk ofdm are studied. on this base, some according solutions to the problem of the different frequency - hopping system are put forward. in the past half of this paper, the realization scheme, pcrforemance and improving measures of ofdm are studied
本文首先較詳細地討論了跳頻抗干擾的能力與調制制度的關系，接著分別研究了幾種常用調制方式（ mfsk ， mpsk ， ofdm ）上述幾方面的性質，針對各跳頻系統存在的問題提出了相應解決方案，在本論文後半部分重點討論了ofdm跳頻系統的實現方案、性能及改進措施。
