WDM驱动程序设计　　 一．WDM简介 　　微软不断推出新的操作系统，现在Windows98和Windows2000已经成了主流，原先用来实现驱动程序的VxD技术随着Win95的淡出也慢慢地将退出历史舞台，在Windows98和Windows2000中设备驱动程序将根据Windows驱动程序模型（WDM）来设计。WDM通过提供一种灵活的方式来简化驱动程序的开发，在实现对新硬件支持的基础上减少并降低所必须开发的驱动程序的数量和复杂性。 -WDM Driver Design 1. WDM briefed constantly introduce new Microsoft operating system, now Windows 98 and Windows 2000 has become mainstream. originally used to achieve the VxD driver technology with the Windows 95 are slowly fade out to be from the historical stage, in Windows 98 and Windows Device Drivers under Windows Flooding dynamic process model (WDM) to the design. WDM by providing a flexible way to simplify driver development, the realization of new hardware support on the basis of the reduction and cut the need to develop drivers for the number and complexity.

C program to calculate the BER performance of BPSK modulation in an AWGN channel. The program takes the file "BPSK" containing voltage levels and passes it in an AWGN channel with a given SNR. The received message is then Hard decision decoded and the bit error rate is calculated. The BER over different SNR is calculated. THe output values can be used to draw a BER vs SNR(dB) curve.
