Leti implements 5G New Radio on VSORA DSP

  • Author:Ella Cai
  • Release on:2018-09-12
French duo of research institute Leti and semiconductor IP supplier VSORA claim to have demonstrated the implementation of 5G New Radio (5G NR) Release 15 on a new DSP architecture.

Defined by the 3rd Generation Partnership Project (3GPP), 5G NR is the air interface, or wireless communication link, for the next 5G cellular networks.

3GPP Release 15 of the 5G system architecture was only finalised in June 2018, and is seen as an important element in deployment of commercially operational 5G systems.

This is the first implementation of 5G NR Release 15 physical layer on VSORA’s multi-core DSP architecture for implementing complex systems like 5G NR.

The VSORA architecture features a software-defined development flow.

This will allow it to support the requirements of 5G to cover broadband, narrowband and low latency system configurations.

“This new DSP development flow allows signal-processing engineers to evaluate different implementations of their algorithms for cost, processing power, arithmetic precision and power consumption, well before the physical implementation,” said VSORA CEO Khaled Maalej.

“The same development flow lets algorithm engineers and software engineers share the same environment and source code, dramatically accelerating time-to-market for Release 15 architectures.”

Benoit Miscopein, head of Leti’s wireless broadband systems lab, writes:

“Our demonstration also shows their product can support a system as hungry in terms of computational resources as the 5G NR modem.”

“The approach proposed by VSORA is also flexible in the sense that the DSP can fulfil the requirements of the standard evolution, e.g. Releases 16 and 17, without redesigning a complete architecture.”
