A generalized Bezoutian matrix with respect to a polynomial sequence of interpolatory type

In this note, a generalized Bezoutian matrix with respect to a polynomial sequence of interpolatory type is introduced. The operator representation relative to a pair of dual bases and the generalized Barnett-type factorization formula are derived. An intertwining relation and a Bezoutian reduction to a block diagonal form by congruence via a generalized Vandermonde matrix are presented. Fujiwara-Hermite and Routh-Hurwitz criteria in terms of this generalized Bezout matrix are obtained.     

DSSS数字接收机的AFC算法及其实现

介绍了一种零中频直接序列扩频(DSSS)数字接收机的自动频率控制(AFC)算法及其仿真和实现.该算法从残留载波跟踪解调环的鉴相信号中提取频偏信息,对下变频本振进行AFC,并且可根据对频偏的估计切换环路特性,使环路既有较大的捕获带宽,又具有较好的跟踪和滤波性能.该算法适用于无导频的直扩BPSK信号接收机,其特点是算法复杂度低,特别易于FPGA实现.

六盘山盆地与酒西盆地成藏条件对比

研究认为，六盘山盆地与酒西盆地具有相似的构造演化特征和油气成藏条件。中生代为走滑拉分盆地，发育张扭伸展断层系，新生代为陆内前陆盆地，发育扭压逆冲断裂系；中生代坳陷都发育生烃潜力较好的白垩系烃源岩，具有相似的烃源岩演化特征、生储盖组合条件和油气运聚特征。因此，分析酒西盆地油气藏分布特征和成藏控制因素，有利于认识和预测六盘山盆地的油气分布规律，以便指导下一步的油气勘探。

10-Gb/s error-free transmission under optical reflection using isolator-free 1.3- /spl mu/m InP-based vertical-cavity surface-emitting lasers

Error-free transmission through 10-km single-mode fiber at 10 Gb/s under -13-dB optical reflections has been demonstrated for the first time using a directly modulated 1.3-/spl mu/m InP-based VCSEL without any optical isolator. The 13-GHz relaxation oscillation frequency and stable polarization suppresses relative intensity noise degradation under optical reflection. Only 1-dB error-free power penalty has been observed with optical reflection set with the worst polarization direction.     

A Pervasive Computing Curriculum for Engineering and Science Students

Today, there's an urgent need for well-trained pervasive computing engineers and scientists. Pervasive computing has evolved into a critical field, influencing a broad range of industries from healthcare to manufacturing to defense. However, most computer engineering and computer science programs pay marginal attention, at best, to the field. In this issue, the authors of the Rochester Institute of Technology describes a set of courses on pervasive computing topics and a supporting laboratory designed for both computer engineering and computer science students
