在 Matlab 中生成 WLAN 信号
我正在寻找一些工具,通过它我可以生成/模拟 WLAN(IEEE 802.11 b PHY 层)信号。
我的偏好是在 Matlab 中生成。任何有用的链接或我如何做到这一点的想法都会有很大的帮助。
谢谢, 基兰
I am looking for some tool, through which I could generate / simulate the WLAN ( IEEE 802.11 b PHY layer ) signal.
My preference would be to generate in Matlab. Any useful links or idea how I can do it would be of great help.
Thanks,
Kiran

看看这个:

基本上您需要一个微波 ISM。
希望有帮助

Hope it helps
我来晚了一点,但是驱动(更昂贵)信号发生器的替代方案是驱动更便宜的替代方案。最新的 Simulink 通信模块集 (v5.0 - r2010b )包括对 Ettus Research 的 USRP2 的支持,可以驱动它创建 Wifi (802.11a/b/g) phy 层信号(使用适当的子板 - 例如 RFX2400 和/或 XCVR2450)。请注意,当前版本的模块集不支持较新的 USRP N210 或一些需要 UHD 驱动程序的较新子板(例如 WBX、SBX 等) - 尽管我听说过此类支持可能会包含在下一个版本中。请注意,这使用 Simulink 而不是 Matlab 来连接无线电 - 但由于 Matlab 和 Simulink 可以来回传递变量,因此您应该能够实现您想要的效果。请注意,USRP 系列无线电是通用 SDR(软件定义无线电),因此一旦您发现如何对它们进行编程(例如,通过 Simulink 或 GNURadio,或者完全自定义软件,如果您愿意),您可以让它们生成任何可用瞬时带宽内的射频信号(例如,USRP2 中约为 25Mhz,如果您想重新编程 FPGA,则可以更高),且载波频率受您提供的子板支持。
I'm a little late to the party here, but an alternative to driving a (more expensive) signal generator is to drive a cheaper alternative. The latest Simulink Communications Blockset (v5.0 - r2010b) includes support for Ettus Research's USRP2, which can be driven to create Wifi (802.11a/b/g) phy layer signals (with the appropriate daughterboard - e.g. the RFX2400 and/or the XCVR2450). Note that the current release of the blockset does not support the newer USRP N210, or some of the newer daughterboards that require the UHD driver (e.g. the WBX, SBX, etc.) - although I have heard that such support may make into the next release. Note that this uses Simulink rather than Matlab to interface to the radio - but since Matlab and Simulink can pass variables back and forth you should be able to achieve what you want. Note that the USRP-family of radios are general purpose SDRs (software-defined radios), so once you discover how to program them (e.g. via Simulink, or GNURadio, or completely custom software if you wish), you can make them generate any RF signal within the available instantaneous bandwidth (e.g. about 25Mhz in the USRP2, or higher if you want to re-program the FPGA), and at carrier frequencies supported by the daughterboard you supply.
