This thesis analyzed the error performance of mfsk and mpsk modulator in hf with optimal receiver, studied the shortcoming and strongpoint of several typical short - wave data transmission systems and their performance over fading and intersymbol interference channels. the theory and key technical of adaptive modem is discussed. in the last, an efficient modulation scheme - block coded modulation is introduced into hf radio systems to improve the efficiency of hf data transmission, this paper also proposes a hf data transmission system scheme composed of a block coded modulator and a decision feedback type adaptive equalizer
本文在對短波數傳兩種常見調制方式fsk及psk最佳解調性能分析的基礎上，討論了幾種採用典型調制技術的短波數傳系統（如時頻調制、多進制頻移鍵控慢跳頻、 chess系統）原理、優缺點以及抗衰落和抗符號間干擾的性能；分析了自適應串列數傳系統抗短波通道衰落和多徑干擾的原理、關鍵技術；在本文的最後引入一種有望解決短波數傳系統低效率狀況的調制方式bcm -分組編碼調制，給出了一個採用bcm技術與自適應均衡技術相結合的短波數傳系統方案，並通過計算機模擬進行了初部驗證。Curiously, in addition to graphite and diamiond, the existence of a new kind of elemental carbon in the form of football shaped molecules was predicted as early as the 1960s, but was not confirmed until 1985
在1960年代已有人預言，碳除了以石墨和金剛石即鉆石的形式存在外，並能以足球的形式存在，其後在1985年獲得證實，並引起一連串籠形碳分子即富勒烯的科學研究。A algorithm is presented to identify dynamic crosstalk noise. in the course of dynamic crosstalk noise identification, hybrid timing analysis is used to provide accurate signal arrival time, which can provide more accurate timing information than static timing analysis. at the same time, a novel test generation is chosen to verify the correlation of signals. so dynamic crosstalk noise can be identified by these accurate timing and logic information
提出了動態串擾噪聲的識別演算法.針對基於傳統靜態時序分析的結果過于保守的缺點，本演算法引入了混合時序分析，縮小了時間窗區間，為動態串擾噪聲的識別提供了準確的時序信息，與此同時，通過測試生成來驗證信號間的邏輯關系，根據這些準確的時序及邏輯信息，識別出動態串擾噪聲The paper has begun with existing driving mechanism of horizontal barrel finishing equipment and analysed the reason that creates the family of crank parts machining quality problem. the transmission plan of noncircular gears connect crank - slider mechanism has been presented and mathematical model of driving mechanism has been established. by way of programming operation, simulation analysis and parameter optimization, the feasibility of new plan has been proofed
本課題從現有臥式滾磨設備的傳動機構入手，對造成曲軸類零件加工質量問題的原因進行了分析，提出引入非圓齒輪串聯曲柄滑塊機構的傳動方案，建立了傳動機構的數學模型，通過計算機編程運算及模擬分析和參數優化，驗證了所提新方案是可行的。Analyzed the correlative theory of signal integrity such as reflection, crosstalk, simultaneous switch noise etc in detail, 2. simulated reflection and crosstalk, gave the corresponding waveforms, and summarized the solutions to reducing reflection, crosstalk and ssn, 3. using the method of signal integrity analysis, finished the pcb design of high speed data sampling system independently, 4
本文所完成的工作主要有以下幾個方面: 1 .對引起信號完整性問題的反射、串擾、 ssn進行了較深入的理論分析; 2 .給出了在常見情況下解決信號完整性問題的一些方法，並進行了相應的模擬驗證; 3 .運用信號完整性分析方法，獨立完成了高速數據採集系統pcb板的設計製作; 4 .完成了系統ad部分的調試。Three men, including a former branch manager of the bank of china, were sentenced to jail terms ranging from 15 months to 21 months for their involvement in a bank reference fraud
三名男子，包括一名中國銀行中銀前分行經理，串謀引致中銀發出一封不準確的函件，證明一The flood detention and storage capacity of several billion cubic meters of hongze lake has been recognized for a long time, but the resistance of fiver - lake string has always been ignored, based on an analysis of historical information about flood events, the harmfulness of plain fiver - lake string was revealed, then, the necessity for implementation of fiver - lake separation in regulation of the huaihe river was verified, and a reasonable scheme for fiver - lake separation and a feasible modeling method for scientific demonstration were also put forward
摘要針對長期以來人們只認知洪澤湖的幾十億立方米防洪調蓄能力，卻漠視它的河湖串阻力及其一級尾閭地位的情況，通過對歷史洪水和有關資料的分析，初步揭示平原河湖串的危害性，由此引證進一步治理淮河實施河湖分離的必要性，並提出一種合理的河湖分離方案，以及比較可行的模擬論證方法。分享友人
