Nutaq Announces Joint Collaboration for a 5G Base Station with Viettel

Nutaq Innovations has entered into an agreement with Viettel’s Network Technologies Center (VTTEK) for a joint collaboration program for the development of a 5G Massive MIMO base station prototype. Both organizations are joining forces in this program that covers the implementation of baseband processing for 5G Massive MIMO as well as the design of a [...]

Reciprocity Calibration for Massive MIMO – Part III

Generalized Least Square Method In the previous blog, we have discussed the reciprocity calibration for massive MIMO system using direct-path LS methods, or Argos. The calibration coefficients are estimated by the received signal from the single reference antenna. In this blog, we will show how the generalized LS method is used in the massive MIMO [...]

Configuring the Radio640 Reference Clock

Nutaq’s second generation PicoSDRs utilize our second generation Radio640 FMCs. Radio640 is based on AD9361 RF chip from the Analog devices. In this short application note, we highlight the different options that are available to configure the Radio640 reference clocks. The host APIs, which form part of the Nutaq Board and Software (BAS) software suite, [...]

LTE-based IoT – Demo at Embedded World Conference 2017

This demonstration will be presented at the Embedded World Conference 2017 from March 14-16 in Nürnberg, Germany. Nutaq will be located inside DSPecialist's booth in Hall 4, booth #236. DSPecialist is Nutaq's distributor  in Germany. Demo Description: The Internet of Things (IoT) is one of the hottest topics that industrials and researchers are studying from different theoretical, [...]

Reciprocity Calibration for Massive MIMO -Part II

Statistical Models for Propagation Channels Between Internal BS radios In the first part of this series blogs, we have discovered that the Massive MIMO system can use internal BS radios to achieve reciprocity calibration instead of relying on external calibrations. The focus of reciprocity calibration is to find out the calibration coefficients bp. A method [...]

Xilinx System Generator Implementation of Physical Layer Security on Nutaq SDR

Xilinx System Generator Implementation of Physical Layer Security on Nutaq SDR   Security of wireless communication systems has always been a concern and, as a result, a rich field for research. Traditionally, security features, like cryptography, are added to the upper layers of wireless communications protocol stacks.   Cognitive Radios is a wireless communication system which [...]

Nutaq at Mobile World Congress (MWC) 2017

  Are you going to MWC 2017 at the end of the month? If you are and would be interested in learning more about our different solutions, you can either pass by NuRAN Wireless booth #7H40 (Nutaq is a wholly owned subsidiary of NuRAN Wireless) from Monday to Wednesday or even better, fill out the [...]

Reciprocity Calibration for Massive MIMO – Part I

Reciprocity Calibration for Massive MIMO -Part I Introduction In modern communication systems, pilot symbols are transmitted from every antenna of a base station (BS) in the downlink channel and received at the terminal side, then sent back to the BS with channel state information (CSI) to calculate pre-coding coefficients. In Massive MIMO system, such a [...]
