IQ Compression for 5G fronthaul




Greater Copenhagen area

5G wireless technology is an essential technology to be launched to meet the rising demands of more connected devices, higher data speeds, rapid response times and high quality of service (QoS). To meet these requirements cost-effectively, an entirely new network architecture must be deployed. Essential to the network architecture will be a Centralized Radio Access Network (C-RAN) where Baseband Processing Units (BBUs) are separated from Remote Radio Heads (antennas - RRHs) and physically or virtually centralized in order to increase efficiency and cost-effectiveness.

To bring down bandwidth requirements between the BBU’s and the RRH’s several standards are proposing splitting the radio protocol stack, so that parts of the L1/PHY processing is taking place at the RRH side. In addition to splitting the radio protocol certain standards are also applying different compression schemes to further reduce the bandwidth.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.

Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
