The objective of the project is 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:
The demonstrator supports user bit rates up to 5.6 Gbps for 16APSK modulation, while the design is prepared for higher order modulation and higher user bit rates.
The main challenges in the project is the high baud rate, the high bandwidth and the high user data rate.
The DVB-S2X modem that is developed in this project supports significantly higher baud rates and larger bandwidths than any other commercially available products, and demonstrators, available in 2018. The modem will allow more efficient use of wideband links where a single DVB-S2X carrier now can be used in place of multiple 250-500 MHz DVB-S2X carriers.
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.
The duration of the project is 24 months.
The modem design has been completed and the modem hardware has been manufactured, verified and is available in the lab. Currently the modem firmware and software implementation is ongoing (80% completed).
The next milestone is the Test Readiness Review (TRR).
