More Information Accept X. The experiment’s feedback should also be interesting for standardisation groups, space agencies and institutions, academics and equipment dvn working on the DVB-S2 subject.

Leveraging the ZPU, the modem control block is able to perform algorithms required for ACM, gain control, and other real-time functions. The space and ground segment and other test equipment are specified in detail together with the link budgets.

On average, the E2IQ performance liopback is 0. Results are reported and published in several dissemination documents, including a feedback to the standardisation group and an article for a conference.

Loopback Fading

Taking into account outcomes from previous loolback, simulations and studies, as well as operators experience feedback and perspectives on DVB-S2, the main test areas are:. The main objective of the DVB-S2 Satellite Experiment project is to perform an in-depth verification and optimisation by satellite of the many new features present in the DVB-S2 standard, such as high order modulations, enhanced coding ooopback ACM, through extensive test campaigns consisting of svb trials and measurements.

Application Test run and display of measurement results The test cases are first configured on the connected PC via the graphical user interface. For signal generators that support loopback of markers, the PXB passes them through from input to output. The three test platforms are based on the DVB-S2 end-to-end communication chains that include gateway hubs and user equipment receivers, set-top boxesand the operator’s space and ground segments.

The outcome of the experiments will concern primarily the operators wishing to move to DVB-S2 for their applications HDTV, interactive and professional services, etc. Using Markers with Loopback Fading.

Finally, the center frequency and transmit power level may be configured via the SPI bus using a modem control liopback or by the host. A diagram showing our hardware configuration is captured in Figure 2. Skip to main content. The project consortium, led by the satellite manufacturer Astrium Satellites, includes the participation of operators Eutelsat and Telesat and other partners involved in satellite telecommunications DLR, Fraunhofer IIS and Nera.

Before starting, the desired test loopbck are selected from the test cases library.

Contact National Delegations Newsletter Register. After the test run is completed, the results are displayed in reports which can be saved as well as evaluated and exported in a variety of ways. Since the Master Channel is set to the IO port that’s connected to your signal generator, markers will come into the IO port, pass through the fader, and return through the same IO port as an output to the signal generator.

The following theoretical performance gains are expected to be obtained in real satellite operation: The digital baseband IQ signals to be faded are created on a vector signal generator using internal signal creation personalities, Signal Studio applications, or custom waveforms created by mathematical modeling tools.

Objectives The main objective of the DVB-S2 Satellite Experiment project is to perform an in-depth verification and optimisation by satellite of the many new features present in the DVB-S2 standard, such as high order modulations, enhanced coding and ACM, through extensive test campaigns consisting of field trials and measurements.

The sum signal is made available to multiple instruments. Challenges The experiments assess and provide results on the critical aspects of the operation of DVB-S2 by satellite in terms of functional behaviour and performance. Driven by the host, the purpose of the control flow is to configure and calibrate the encoder, modulator, and RF front end.

A block diagram of our E2IQ core is shown in Figure 3. Through these efforts, it is our objective to demonstrate to C4ISR users the flexible adaptability of using our E2IQ core in next generation systems.

Three platforms corresponding to the loopbac profiles of the DVB-S2 standard – broadcast, interactive and professional – are set up to achieve the following objectives:.

The second and final part of test campaign will use commercial grade equipment with advanced Quality of Service traffic shaping device controlled by the network management system upgraded for ACM operation. The test cases have a koopback structure and can be documented in easy-toreproduce, editable reports.

Test results are being analysed and reported.
