Channel Emulation software development tools

RF channel emulation (8-tap) covering V2X standard emulation scenarios. Combinable with V2X communication protocols. Full LabVIEW API for emulation parameter control. Interactive control interface. Applicable to NI software defined radios (USRP or VST Gen. 1). For V2X Add-Ons 802.11p & LTE-V. DetailsThe package is designed to simulate Doppler shift, fading and multipath effects for RF. This software add-on provides the capability to combine all the effects of a signal on 8 different propagation paths (8-tap) in real-time as standalone or in combination with SEA V2X communication add-ons based on NI software defined radios.RF-transmissions are distorted by real world effects altering the wave fronts. These distortions seriously affect the quality and performance of wireless information transmission, especially in traffic oriented RF-applications like V2X. The emulation of these effects is required to test and validate the robustness of receiver setups and chip sets.Typical major physical propagation effects are:attenuationfading by atmospheric effectsDoppler (frequency) shift by relative motion of transmitter and receivermultipath effects resulting from the wavefront being reflected on objects along the propagation pathThe toolkit represents the distorted RF-wavefront of one transmitter (typically vehicle or other traffic object) at the antenna of a receiver. All emulation parameters can be changed actively by a comfortable LabVIEW API.Parameter sets defined by standardization bodies, e.g. ETSI, can be simulated with the CEM toolkit.This toolkit is also available as standalone package or as an integrated component of S.E.A. V2X turnkey test systems for functional testing, RF-behavior measurements and customer specific automated test systems.More Information

Simulate dense traffic/stress LTE-V communication up to the theoretical limit of LTE-V. Catch LTE-V messages for extended monitoring and testing (even invalid frames). Inject erroneous messages overriding MAC control and timing (even with corrupt frame content). Generate precisely timed LTE-V message streams for LTE-V and V2X validation. Get precise timestamps of Rx and Tx activities (coupled to a user-configurable reference clock). Synchronize LTE-V message streams to other signals such as CAN, GNSS simulation, and more. Contains the Channel Emulation function package. DetailsThe LTE-V MONITORING delivers unique access to the 3GPP TS 36.300 (Release 14 / Mode-4 sidelink) standard in LabVIEW™ for the future V2X (Vehicle-To-Anything) communications based on NI™ hardware platform NI USRP. It includes (a) a LabVIEW API (functions palette) incl. examples for programming LTE-V-based applications in LabVIEW and (b) the Host Control Manager (HCM) for interaction with the local communication hardware. It contains the Channel Emulation function package.The MONITORING package enables transmission (send + receive) of regular LTE-V packets (MAC + PHY layer) and offers precise timing of the MPDU-packet output as well as precise time information of the received packets. In addition the package adds features for failure injection by data and timing manipulation (Packet Replay) as well as monitoring of the data traffic using standardized protocol TZSP.At present following hardware is supported:NI USRP-2953NI USRP-2954The package is designed for high-load communication, in-depth stressing and debugging the functionality of LTE-V-capable devices in development, validation and research applications.For the API LabVIEW 2014 or higher (development version) is required. The HCM requires LabVIEW 2015 Run-Time Engine as well as suitable device drivers (NI USRP or NI VST), version 15.More Information
