Linux 虛擬網(wǎng)絡(luò)接口 實例 In the Linux (or Unix) world, most network interfaces, such as eth0 and ppp0, are associated with a physical device that is in charge of transmitting and receiving data packets. However, some logical network interfaces don t feature any physical packet TRanSMISSION. The most well-known examples of these "virtual" interfaces are the shaper and eql interfaces.

zemax源碼： This DLL models a standard ZEMAX surface type, either plane, sphere, or conic The surface also demonstrates a user-defined apodization filter The filter is defined as part of the real ray trace, case 5 The filter can be used at the stop to produce x-y Gaussian apodization similar to the Gaussian pupil apodization in ZEMAX but separate in x and y. The amplitude apodization is of the form EXP[-(Gx(x/R)^2 + Gy(y/R)^2)] The TRanSMISSION is of the form EXP[-2(Gx(x/R)^2 + Gy(y/R)^2)] where x^2 + y^2 = r^2 R = semi-diameter The tranmitted intensity is maximum in the center. T is set to 0 if semi-diameter < 1e-10 to avoid division by zero.

In this edition, the majority of the book is dedicated to covering the Winsock API. Chapter 1 starts with an introduction to Winsock and is specifically geared for the beginning Winsock programmer. This chapter covers all the basics and introduces TRanSMISSION Control Protocol (TCP) and User Datagram Protocol (UDP) through simple samples, as well as providing a roadmap to advanced Winsock topics covered in other chapters. For the sake of simplicity, Chapter 1 covers the IPv4 protocol.

The purpose of this application note is to describe the main elements of an RS-422 and RS-485 system. This application note attempts to cover enough technical details so that the system designer will have considered all the important aspects in his data system design. Since both RS-422 and RS- 485 are data TRanSMISSION systems that use balanced differential signals, it is appropriate to discuss both systems in the same application note. Throughout this application note the generic terms of RS-422 and RS-485 will be used to represent the EIA/TIA-422 and EIA/TIA-485 Standards.

Carrier-phase synchronization can be approached in a general manner by estimating the multiplicative distortion (MD) to which a baseband received signal in an RF or coherent optical TRanSMISSION system is subjected. This paper presents a unified modeling and estimation of the MD in finite-alphabet digital communication systems. A simple form of MD is the camer phase exp GO) which has to be estimated and compensated for in a coherent receiver. A more general case with fading must, however, allow for amplitude as well as phase variations of the MD. We assume a state-variable model for the MD and generally obtain a nonlinear estimation problem with additional randomly-varying system parameters such as received signal power, frequency offset, and Doppler spread. An extended Kalman filter is then applied as a near-optimal solution to the adaptive MD and channel parameter estimation problem. Examples are given to show the use and some advantages of this scheme.
