A passive optical network (PON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 32-128. A PON consists of an Optical Line Termination (OLT) at the service provider s central office and a number of Optical Network Units (ONUs) near end users. A PON configuration reduces the amount of fiber and central office equipment required compared with point to point architectures

開源備份軟件源碼 AMANDA, the Advanced Maryland Automatic Network Disk Archiver, is a backup system that allows the administrator to set up a single master backup server to back up multiple hosts over network to tape drives/changers or disks or optical media. Amanda uses native dump and/or GNU tar facilities and can back up a large number of workstations running multiple versions of Unix. Amanda uses Samba, Cygwin or a native Windows client to back up Microsoft Windows desktops and servers

輸入、輸出功能,檢驗輸入的數是否為數字功能,ASCII碼與二進制數的的相互轉化功能,兩數相乘功能,因此整個程序定義了兩個宏INPUT和MULTIPLE,宏INPUT實現了輸入、檢驗和ASCII碼與二進制的相互轉換功能,MULTIPLE實現了兩數相乘功能,實現輸出功能的是子程序OUTPUT,由于在輸入的過程中多次用到了回車換行,因此定義了一個回車換行子程序CRLF。

The C++ Editor is a text editor for C++ programmers. The editor have color syntax highlighting. Editor s main purpose is to edit source code files outside the IDE (Integrated Development Environment) with multiple opened copies of program, when programmer needs to find, replace or compare source code. The program can compile the file using for this purpose the Microsoft VC compiler. Most effectively the editor can be used with a file search utility. The search utility Search&Edit or IDE Helper is available for download on developer s WEB site (http://www.easydevtools.com/dwnl_frame.htm).

Java technology is both a programming language and a platform. The Java programming language originated as part of a research project to develop advanced software for a wide variety of network devices and embedded systems. The goal was to develop a small, reliable, portable, distributed, real-time operating platform. When the project started, C++ was the language of choice. But over time the difficulties encountered with C++ grew to the point where the problems could best be addressed by creating an entirely new language platform. Design and architecture decisions drew from a variety of languages such as Eiffel, SmallTalk, Objective C, and Cedar/Mesa. The result is a language platform that has proven ideal for developing secure, distributed, network-based end-user applications in environments ranging from network-embedded devices to the World-Wide Web and the desktop

This project demonstrates the use of secure hash functions technique to implement a file encryption / decryption system. This implemented application can encrypt / decrypt multiple files on the fly using a password. The password supplied by the user is used as the source message from which the hash code (key) is generated using the SHA algorithm. Then this key is used to enctypted the data in the file(s). This key is stored in the encrypted file along with the encrypted data.

In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model. Based on this model, we derive the weight vector and the output signal-to-interference ratio (SIR) of the MMSE receiver. The effects of quantization on the MMSE receiver performance is characterized in a single parameter named 鈥漞quivalent noise variance鈥? The optimal quantizer stepsize which maximizes the MMSE receiver output SNR is also determined.
