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 (链表).

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 ...

基于OFDM的无线宽带系统仿真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 f ...

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 wi ...
