Software Based MIMO Channel Emulator
Source: Wireless Innovation Forum
Fox is a software based channel emulator that models a wireless channel with up to 4x4 MIMO paths. While currently supporting 802.11n channel models, Fox can be extended to incorporate other channel models, including LTE and a variety of military or proprietary models. Fox works on MIMO streams of IQ samples and operates in the National Instruments LabVIEW application development and graphical programming environment. Fox takes as input a sampled 802.11n baseband signal stored in a file, mathematically applies 802.11n channel models and other distortion to this signal and outputs the resulting signal to a file.
