Rapid-Acquisition-of-Doppler-Shift-
本文提出了一种适用于低轨卫异扩频通信系统的多普勒频移快捕方法.该方法基于数字匹配滤波器及自动频率控制环路_利用数字匹配滤波器的囚码快捕特性及其输出主相关峰值对频偏的敏感性,缩短多普勒频移的
捕获时间.论文首先推导了多普勒频移的平均捕获时间表达式,然后根据数值分析结果得到了准最佳捕获判决策略,最后通过比较验证了该快捕方法相对于传统串行捕获方法在性能上的提高.
(This paper presents a low-orbit health for different spread spectrum communication system fast catching the Doppler shift method, which based on digital matched filter and automatic frequency control loop _ prisoners using digital matched filter code features rapid acquisition and the output of the main correlation peak frequency deviation of the sensitivity of the Doppler frequency shift to shorten acquisition time. paper first derive the mean Doppler shift acquisition time expression, then the numerical results obtained quasi-optimal capture decision strategies, and finally verified by comparing with the rapid acquisition method to capture the traditional method of serial improvement in performance.)

Diffusion-system-of-concentration-
扩散系统之浓度分布的装置。管中储放静止液体B,高度为L=10 ㎝,放置于充满A 气体的
环境中。假设与B 液体接触面之浓度为3
C 0 0.01mol m A = ,且此浓度不随时间改变
而改变,即在操作时间内( h = 10天)维持定值。气体A 在液体B 中之扩散系数为
D m s AB
= 2×10− 9 2 。试决定以下两种情况下,气体A溶于液体B中之流通量(flux)。
(a) A 与B 不发生反应;
(b) A 与B 发生以下之反应
A+ B→C , A A − r = kC
其反应速率常数k = 2×10− 7 s− 1。
(Diffusion system of concentration reference device shown in Figure 3. Tube in the store still liquid B, L = 10 cm height, placed in full A gas environment. Assuming the contact surface of the liquid with the B concentration of 3 C 0 0.01mol m A =, and this concentration does not change with time and change, that is, the operating time (h = 10 days) to maintain constant. Gas A in liquid B, the diffusion coefficient D ms AB = 2 × 10-9 2. Decided the following two test cases, the gas dissolved in liquid B in the A liquid (flux). (A) A and B do not react (b) A and B of the following reaction occurs A+ B → C, AA- r = kC, the reaction rate constant k = 2 × 10-7 s-1.)
