This is GPS Matlab acquisition code. Function performs cold start acquisition on the collected "data". It searches for GPS signals of all satellites, which are listed in field "acqSatelliteList" in the settings structure. Function saves code phase and frequency of the detected signals in the "acq ...

Introduction Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-erro ...

We analyze, both analytically and numerically, the effectiveness of cloaking an infinite cylinder from observations by electromagnetic waves in three dimensions. We show that, as truncated approximations of the ideal permittivity and permeability tensors tend towards the singular ideal cloaking fiel ...

In an electromagnetic cloak based on a transformation approach, reduced sets of material properties are generally favored due to their easier implementation in reality, although a seemingly inevitable drawback of undesired reflection exists in such cloaks. Here we suggest using high-order transforma ...

We obtained the energy transport velocity distribution for a three dimensional ideal cloak explicitly. Near the operation frequency, the energy transport velocity has rather peculiar distribution. The velocity along a line joining the origin of the cloak is a constant, while the velocity approaches ...

This book brings together indispensable knowledge for building efficient, high-value, Linux-based embedded products: information that has never been assembled in one place before. Drawing on years of experience as an embedded Linux consultant and field application engineer, Christopher Hallinan offe ...

签于目前市场上结合Query万能查询的第三方控件，适合DELPHI的特别多，如武稀松先生的WNQUERY，但适合CBUILDER的几乎是麟毛凤脚，由于公司产品上需要用到该功能，所以特别花了一天时间编了这个适合CBUILDER6版本的万能查询模块（如有需要亦可提供CBUILDER5的版本），供大家参考使用，改天有时间我会推出该系列的第三方控件， ...

TC35i模块有40个引脚，通过一个ZIF(Zero Insertion Force，零阻力插座)连接器引出。这40个引脚可以划分为5类，即电源、数据输入/输出、SIM卡、音频接口和控制。
