WilDCAT
WilDCAT Project
Waveform Design and benChmArking Tool
The WilDCAT objective is to design and develop a unified transmitter and receiver scheme able to accommodate all the best known multicarrier modulation waveforms beyond OFDM. The WilDCAT tool will be able to switch between waveforms with simple change of parameter settings. It will be implemented for use on general purpose Software Radios with hardware and software tools offered by ORCA. The WilDCAT tool can be used to:- Provide real-time reconfiguration between waveforms and receiving functions.
- Evaluate waveforms and benchmark possible implementations in terms of spectral efficiency, interference management and tolerance in RF impairments.
- Design new waveforms that combine features in the use of filter-banks, windows, cyclic extensions, tail biting etc.
- Design and test unified transmission and reception functions that can be straightforwardly applied to all supported multicarrier waveforms.
ORCA testbed facilities provide complementary capabilities to enable innovative communications research. The “Online Wireless Lab (OWL)” testbed of the TU Dresden Vodafone Chair supports the experimental investigation of technologies for next generations of wireless communications systems. The WilDCAT project has access to OWL in order to validate through a series of experiments the WilDCAT tools. OWL supports the jFed experimentation tool. On the reservation webpage, WilDCAT project members check the availabilities of the resources and reserve them for the experiments. The experiment server will prepare the remote access basing on the reservation information and the operation commands from jFed from the user side. Upon scheduled start time, the WilDCAT project members can remotely access the testbed.
