产品描述
Because of its capacity-approaching forward error correction, today DVB-S2 is the de-facto standard in satellite communication and other applications. The Creonic DVB-S2 IP core integrates the forward error correction as defined by the standard (including LDPC and BCH decoder).
主要特性与优势
- Compliant with ETSI 302 307 V1.2.1 (2009-08) (DVB-S2).
- Supports ACM, CCM, and VCM modes.
- Support for short blocks (16200 bits) and long blocks (64800 bits).
- Support for all modulation schemes (QPSK, 8-PSK, 16-APSK, 32-APSK).
- Support for all interleaving schemes of all modulation schemes.
- Support for all LDPC and BCH codes as defined by the standard.
- Decoder contains soft-decision demapper, block deinterleaver, LDPC decoder, BCH decoder, and descrambler.
- Design-time configuration of throughput for optimal resource utilization.
- Low-power and low-complexity design.
- Burst-to-burst on-the-fly configuration.
- Faster convergence due to layered LDPC decoder architecture.
- Collection of statistic information (number of modified information bits, number of iterations, decoding successful).
