Real-Time DSP for High-Speed Communication
Customizable IP Cores for Maximum Channel Capacity
The IP Cores enable real-time implementation of DSP algorithms to mitigate transmission impairments and maximize channel capacity. They are fully customizable and have been successfully tested on various state-of-the-art FPGAs.
DLFi – The Distributed Learning Framework
Privacy-preserving AI-as-a-Service solution for distributed machine learning
DLFi enables the training of ML models at remote sites without the need to move or transfer data. This ensures data owners' privacy and promotes collaboration among different data providers. Key features include cloud-native architecture, modularity, customizable dashboards, and GPU support.
Data Sharing for Autonomous Networks
Real-time data for the development of smart network solutions
Our datasets from real-world networks enable researchers and providers to develop and validate solutions for autonomous networks. The standardized and cleaned datasets include 4G/5G RAN data and are ideal for applications such as training machine learning algorithms and developing network automation solutions.
VPItoolkit™ DSP Library
Comprehensive DSP algorithms for coherent optical systems
The VPItoolkit™ DSP Library offers an extensive collection of lab-proven digital signal processing algorithms for coherent optical systems. It supports a wide range of modulation formats such as (DP) BPSK, (DP) QPSK, PS QPSK, (DP) mQAM, and probabilistically shaped QAM. Features include I/Q imbalance correction, clock recovery, polarization demultiplexing, and PMD compensation. Seamless integration into VPItransmissionMaker Optical Systems and VPIlabExpert enables efficient simulations and analyses.
