5TIME-VARYING AR MODELING AND ADAPTIVE IIR NOTCH FILTER FOR ANTI-JAMMING DSSS RECEIVER显示文摘Using Time-Varying AR (TVAR) model and adaptive notch filter is a new method for the non-stationary jammer suppression in Direct Sequence Spread Spectrum (DSSS). The performance of TVAR model for Instantaneous Frequency (IF) estimation will be affected by some factors such as basis functions. Focusing on this problem, the optimal basis function of TVAR model for the IF estimation of the LFM signal is obtained in this paper. Besides the depth and width of notching, the phase properties of notch filter affect the Signal-to-Interference plus-Noise Ratio (SINR) of correlation output to the narrowband jammer suppression in DSSS, in response to the problem the closed solution of correlation output SINR improvement has been derived when a single frequency jammer passes through direct IIR notch filter, and its performance has been compared with those of five coefficient FIR filters. Later, a novel method for LFM jammer suppression based on Fourier basis TVAR model and direct IIR notch filter is proposed. The simulation results show the effectiveness of the proposed method.Feng Jining Yang Xiaobo Diao Zhejun W.u. Siliang 2010Journal of Electronics(China)2010,27,4:0
6创伤后成人呼吸窘迫综合征的流行病学研究显示文摘背景:尽管成人呼吸窘迫综合征是钝性创伤早期重要的并发症,但是对其流行病学和发生危险因素的研究仍很欠缺。本研究的目的是通过对一组受伤后住院的病例进行前瞻性队列研究,来分析这种并发症的患病率和人口统计学特点,同时也研究了损伤的严重程度和类型对这种并发症发生的影响。我们的目标是通过确定成人呼吸窘迫综合征发病的高危因素.研究出便于早期发现该征的途径:方法:我们对8年多来收住在同一所大学医院的7192例创伤性损伤的病例进行了前瞻性研究。除髋部骨折和72小时内出院的病例外,所有创伤后需要住院,年龄在13岁以上,并且是医院属区的居民的病例都包括在本研究之内。对肌肉骨骼系统、胸部、腹部和头部创伤,包括单一或复合性创伤的病例,进行创伤后成人呼吸窘迫综合征的患病率和人口统计学的研究。根据创伤类型分析这种并发症的发病相关危险因素。应用多元logistic回归分析确定成人呼吸窘迫综合征发病的最重要的预测因素。结果:36例(0.5%)患者并发成人呼吸窘迫综合征。年轻人患病率明显较高(p=0.002),其中83%继发于高能量创伤。单一的胸部、头部、腹部或四肢创伤的成人呼吸窘迫综合征的患病率〈1%。两个解剖区域损伤者患病率较高(高达2.9%),三个解剖区域损伤者患病率更高(达10.2%):多元logistic回归分析显示:入院时损伤严重程度评分、股骨骨折、腹部和四肢联合损伤、以及入院时观察到的生理功能受损均是后期并发成人呼吸窘迫综合征的各自独立的预测因素。结论:成人呼吸窘迫综合征的患病率随损伤的严重程度和所涉及解剖区域损伤的增加而上升。我们已经能够对这些损伤的重要性和相关危险因素进行量化:我们还对此研究结果对便于早期发现这种并发症的意义进行了讨论。TIMOTHY O.
