Kick-off meeting of QCSP: Quasi Cyclic Small Packet

New ANR cooperative research project

Published 10/10/2019

The IAS team is leading QCSP, an ANR cooperative research project, started on 1st October 2019 with a duration of 42 months.
The kick-off meeting was held in Lab-STICC premises, Lorient, on 3 October, 2019.

The QCSP project aims to contribute to the evolution of IoT networks by defining, implementing and testing a new coded modulation scheme dedicated to IoT networks. The “big bet” of the project is to work on the emergence of non-binary (NB) codes combined with a cyclic code shift-keying (CCSK) modulation. This new coded modulation scheme, called CCSK-NB-code, can be easily implemented in a cost efficient way at the device side. CCSK-NB-code provides several advantages compared to state of the art waveforms: it offers self-synchronization and self-identification capabilities, and is able to operate at ultra-low signal-to-noise ratios (SNR). The ambition for the industrial partners of this project is to provide an input to the 3GPP standardization committee built from the results of the QCSP project. These results are expected, at least, to initiate discussions around the efficiency of such a solution for IoT and to push CCSK-NB-Code in a future 3GPP release, if the project is able to rally enough support from other industrial partners.

The objectives of the QCSP project:

  • Objective 1: Construction of efficient NB codes with excellent performance at low to ultra-low coding rate (rate 1/3 down to rate 1/256). Three families of NB error control code will be studied and compared in terms of performance and complexity: NB turbo code, NB LDPC code and NB polar code.
  • Objective 2: Definition of efficient detection and synchronization algorithms by considering the whole frame itself as a preamble thanks to the particular structure of NB CCSK frames.
  • Objective 3: Development of two demonstrators, one using GNU radio module to perform real time demonstration, the second integrating new modules in Open air Interface, the 5G software alliance for democratizing wireless innovation.
  • Objective 4: The last objective is the dissemination of the results of the project with a particular focus on the 3GPP standards.

The QCSP consortium:

  • AcademiaLAB-STICC/UBS Lorient (project leader), IMS Bordeaux, ETIS Cergy-Pontoise, LAB-STICC/IMT Atlantique Brest, BIU (International University of Beirut) Beirut.
  • Research center: CEA-LETI Grenoble
  • Industry: Orange Labs Meylan, Sequans Paris.
