bpsk调制仿真，可直接用 1、数字调制方法 数字调制就是把数字基带信号的频谱搬移到高频处，形成适合在信道中传输的带通信号。基本的数字调制方式有振幅键控（ASK）、频移键控（FSK）、绝对相移键控（PSK）、相对（差分）相移键控（DPSK）。在接收端可以采用想干解调或非相干解调还原数字基带信号。 数字信号的传输方式分为基带传输和带通传输。然而，实际中的大多数信道（如）无线信道具有丰富的低频分量。为了使数字信号在带通信道中传输，必须用数字基带信号对载波进行调制，以使信号与信道的特性相匹配。(1, digital modulation method Digital modulation is the transfer of the spectrum of a digital baseband signal to a high frequency to form a bandpass signal suitable for transmission in the channel. The basic digital modulation methods are amplitude keying (ASK), frequency shift keying (FSK), absolute phase shift keying (PSK), and relative (differential) phase shift keying (DPSK). At the receiving end, the digital baseband signal can be restored by using dry demodulation or non-coherent demodulation. Digital signal transmission methods are divided into baseband transmission and bandpass transmission. However, most channels in practice, such as wireless channels, have rich low frequency components. In order for a digital signal to be transmitted in a band channel, the carrier must be modulated with a digital baseband signal to match the signal to the characteristics of the channel.)

Slide for beginning with OPNET

说明：  近两天由于研发需要OPNET这个仿真软件，同时要求可以支持wimax仿真模型，对该仿真软件的研究还需要继续进行 好不容易在网络上找到了最新版的OPNET 14.5的软件，但是安装的确出现了很大的麻烦，最后通过查阅网络上对之前版本安装的经验解决了安装过程中的问题，因此将这些分享给大家： (Almost two days because of this R &amp D needs OPNET simulation software, also required to support wimax simulation model, the simulation software is also the need to continue the network finally found the latest version of the OPNET 14.5 software, but certainly there was an installation much trouble, and finally access to the network through the installation of the experience of the previous version to solve the problems during the installation process, it will share all of these:)
