Time delay measurement in the frequency domain
Pump-probe studies at synchrotrons using X-ray and laser pulses require accurate determination of the time delay between pulses. This becomes especially important when observing ultrafast responses with lifetimes approaching or even less than the X-ray pulse duration (∼100 ps). The standard approach of inspecting the time response of a detector sensitive to both types of pulses can have limitat...
متن کاملFinite time stabilization of time-delay nonlinear systems with uncertainty and time-varying delay
In this paper, the problem of finite-time stability and finite-time stabilization for a specific class of dynamical systems with nonlinear functions in the presence time-varying delay and norm-bounded uncertainty terms is investigated. Nonlinear functions are considered to satisfy the Lipchitz conditions. At first, sufficient conditions to guarantee the finite-time stability for time-delay nonl...
متن کاملDelay Spoofing Reduction in GPS Navigation System based on Time and Transform Domain Adaptive Filtering
Due to widespread use of Global Positioning System (GPS) in different applications, the issue of GPS signal interference cancelation is becoming an increasing concern. One of the most important intentional interferences is spoofing signals. An effective interference (delay spoof) reduction method based on adaptive filtering is developed in this paper. The principle of method is using adaptive f...
متن کاملThe Transmission Performance of Multi-code DS-CDMA with Frequency-Domain Equalization using Space-Time Cyclic Delay Transmit Diversity
時に送信する循環遅延送信ダイバーシチ(CDTD)では,等価的にパス数を増加することができるため,大きな周波数ダイバ ーシチ効果が得られる.また,時空間符号化を行い送信する時空間送信ダイバーシチ(STTD)は,アンテナダイバーシチ効 果を得ることができるため,平均ビット誤り率(BER)を改善できる.本論文では,STTD と CDTD を組み合わせた時空間循環 遅延送信ダイバーシチ(STCDTD)を提案し,周波数領域等化を用いる直交マルチコード DS-CDMA に適用したときの平均 BER 特性を計算機シミュレーションによって明らかにしている.また CDTD および STTD の平均 BER 特性と比較をしている. キーワード マルチコード DS-CDMA,周波数領域等化,循環遅延送信ダイバーシチ(CDTD), 時空間送信ダイバー シチ(STTD),時空間循環遅延送信ダイバーシチ(STC...
متن کاملFrequency domain equalization space-time block-coded CDMA transmission system
In this work we propose a space-time block-coded (STBF) CDMA transmission system suitable for use with frequency domain equalization (FDE) algorithms. We illustrate the FDE by implementing the maximal ratio combining, the zero forcing and the minimum mean squared error single user detection algorithms. A diversity gain analysis is developed and some interesting results are pointed out. It is sh...
