Type: 
Research

Duration: 
2017-2019

CARMEN is a three-year (2017-2019) research project sponsored by Gobierno de España (TEC2016-75067-C4-1-R). CARMEN addresses two major trends in current wireless networks: radio interfaces with unprecedented high data rates and Wireless Sensor Networks (WSN). CARMEN aims at developing advanced coding (joint source channel coding, polar coding, correlated information, network coding) and signal processing (unconventional MIMO transceiver architectures, improper signaling schemes for interference-limited scenarios, multiuser architectures for non-coherent transmissions, and distributed signal and information processing over networks and graphs) techniques for emerging wireless communication and sensor networks. CARMEN will also carry out experimental evaluation of coding and signal processing techniques by means of Over The Air (OTA) transmissions and simulations.
