DVB-RCS (Digital Video Broadcasting - Interaction channel for satellite distribution systems) is an established ETSI standard for digital data transmission via satellites. It uses a 8-state double-binary turbo code that has an excellent error correction performance. This outstanding performance of the DVB-RCS turbo codes makes it the ideal candidate for further applications where high spectral efficiency is key for lowering costs.
DVB-RCS Turbo Decoder
Overview
Key Features
- Compliant with ETSI 301 790 V1.4.1 (2005-09) (DVB-RCS)
- Support for all turbo code block lengths (12 to 216 bytes) and code rates (1/3 to 6/7) as defined by the standard
- Support for QPSK and 8-PSK interfacing
Benefits
- Gains up to 4 dB compared to convolutional codes.
- Design-time configuration of throughput, input bit widths, and maximum block length for optimal resource utilization.
- Low-power and low-complexity design.
- Burst-to-burst on-the-fly configuration.
- Configurable interleaver parameters allow for support of custom block lengths.
- On-the-fly bit error rate measurement.
- High block length and code rate granularity.
- Configurable amount of turbo decoder iterations for trading-off throughput and error correction performance.
- Allows for easy migration from legacy DVB-RCS turbo decoders.
- Allows for turbo synchronization to further improve error correction performance (on request).
- Available for ASIC and FPGAs (Xilinx, Intel).
Applications
- Satellite communication (Interactive Services, Professional Services, TDMA)
