WIMIS
Development of wideband modem and internet switch
Project funded by:
Start date: Apr. 2017
Duration: 3 years 9 months
PROJECT OVERVIEW
The project is focussed on hardware acceleration of high-end telecommunication systems. The project is divided to two major parts:
-
Physical layer hardware implementations for satellite DVB-S2(x) and terrestrial 5G NR standards
The major research was focussed on novel hardware architectures for quasi-cyclic LDPC decoders and encoders, as well as modulator and demodulator. -
Development of high-end internet switch
The major research was on development of novel architecture and implementation of a spaceborne router integrated on an FPGA. The router supported high bit-rate satellite links: 10 Gbps satellite-to-ground links and 100 Gbps intersatellite links.
