Multiple Application Support

EB Propsim fading emulators are designed to emulate real-world radio channel environment. They apply the air interface effects to the input signals. These air interface effects include fast fading, shadowing and interferences. EB Propsim radio channel emulators are application independent and can be used for testing various wireless communication technologies, both standardized and proprietary. Application independency is accomplished by wide selection of standard channel models as well as with flexible channel modeling tools.

File-Based Emulation

EB Propsim radio channel emulators use file-based emulation. This enables repeatable fading conditions by enabling running exactle the same frequency selective fading situations independent of time again and again. File-based emulation provides the possibility to freeze the emulation to a specific channel state making it possible to go through the whole emulation in a step-by-step mode. This allows users to debug the system behaviour in a specific part of the whole emulation. File-based emulation makes it possible to use measured radio channel data or data from modeling tools such as MATLAB. It is also possible to export the radio channel emulations from EB Propsims for analysis in e.g. MATLAB.

File-based emulation as well as the various integrated interferences provides unlimited possibilities for emulating any phenomenon encountered in the radio channel, and it does not restrict the emulations solely to the statistical definitions of fading characteristics. Therefore, EB Propsim radio channel emulators support any kind of wireless application testing, ranging from standard compiant handset testing to proprietary smart antenna beamforming and multiple input multiple output (MIMO) wireless technologies.

These pages introduce some example applications for EB Propsim radio channel emulators.
