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 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.

3、使用如下命令更改密码： shell> mysqladmin -u root -p password ‘newpass’ Enter Password:******* 出现Enter Password的提示后输入原来的密码oldpass即可。 读者可以尝试其它所有本章介绍的方法。 4、首先以root用户的身份连接到服务器： shell> mysql -u root -p Enter password:******* 出现Enter password提后输入root用户的密码，然后即进入mysql客户机的交互模式，可以看到下面的提示： Welcome to the MySQL monitor. Commands end with or \g. Your MySQL connection id is 4 to server version: 3.23.25-beta-log Type help or \h for help. Type \c to clear the buffer mysql> 然后发布查询，直接键入题目中的语句： mysql> SELECT User,Host FROM mysql.user

The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video. User Manual

The main purpose of this project is to add a new scheduling algorithm to GeekOS and to implement a simple synchronization primitive (semaphore). As you might have already noticed, GeekOS uses a simple priority based preemptive Round Robin algorithm. In this project, you will change this to a multilevel feedback scheduling. In addition, you will provide user programs with semaphores, a means to check the system s current time and a mechanism for passing command-line arguments

8051 Web Server project See Makefile for build notes Written for Keil C51 V5.1 compiler, notes: It uses big endian order, which is the same as the network byte order, unlike x86 systems. Use OPTIMIZE(2)or higher so that automatic variables get shared // between functions, to stay within the 256 bytes idata space
