find the information about a host with the DNS retrieving system calls, such as gethostbyname() and gethostbyaddr().
(2) All the required information are in the hostent structure.
(3) All the aliases and IP addresses of the host is stored in the hostent structure using linked list (鏈表).
This program shows the distributions of the co-channel interference in forward and reverse link in the cellular mobile system with cluster size N, when the mobile subscriber (MS) is at random positions of a cell.
CANopen is a networking system based on the CAN serial bus.
CANopen assumes that the device’s hardware has a CAN transceiver
and CAN controller as specified in ISO 11898.
CANopen profile family specifies standardized communication
mechanisms and device functionality. The profile family is available
and maintained by CAN in Automation (CiA), the international users’
and manufacturers’ group and may be implemented license-free.
基于OFDM的無線寬帶系統仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator.
Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation.
System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.
To fully utilize the available spectrum for a wireless communication
system it is feasible to adapt to different situations
on the channel. In this paper a flexible OFDM
transmitter is presented together with basic theory behind
OFDM transmission. It is shown that high flexibility can
be obtained with a reasonable amount

Part of the design, the FFT-processor, has already
been fabricated and measurement results are presented.
This program may crash your system or run poorly depending on your hardware. The program and code contained in this archive was scanned for virii and has passed all test before it was put online. If you use this code in project of your own, send a shout out to the author!
CRM源碼This file describes some issues that should be implemented in future and how it should be implemented.
Note: it should be implemented exactly how it described below, because another parts of system can rely on it.
The ISO Base Media File Format is designed to contain timed media information for a presentation in a
flexible, extensible format that facilitates interchange, management, editing, and presentation of the media.
This presentation may be ‘local’ to the system containing the presentation, or may be via a network or other
stream delivery mechanism.
A technical trading system comprises a set of trading rules that can be used to generate trading signals. In general, a simple trading system has one or two parameters that determine the timing of trading signals. Each rule contained in a trading system is the results of parameterizations.
