Objectives

The objective of the project was to develop and implement a demonstrator for DVB-S2X wideband transmission links supporting baud rates up to 1.4 Gsps. The following modules are included in the demonstrator:

  • DVB-S2X transmitter
  • Wideband channel emulator
  • DVB-S2X receiver

The demonstrator supports user bit rates up to 4.9 Gbps for 16APSK modulation, while the design is prepared for higher order modulation and higher user bit rates. 

Challenges

The main challenges in the project was the high baud rate, the high bandwidth and the high user data rate.

System Architecture

The architecture of the demonstrator developed in this project is shown in the block diagram below. The same hardware platform is used for both the transmitter and the receiver implementations.

Plan

  • The project was kicked off in June 2018.
  • The System Requirement Review (SRR) was held in September 2018, 
  • The Critical Design Review (CDR) was held in June 2019, 
  • The Test Readiness Review (TRR) was held in  March 2020
  • The project was completed, and the Final Review was held in August 2021. 

Current Status

The project is completed.
