DVB-S2X Compliant LDPC/BCH Encoder IP Core
The AHA4709E LDPC/BCH forward error correction (FEC) encoder core supports all codes, frame sizes, and interleave schemes set forth in the DVB-S2X specifications for broadcast, interactive, digital satellite news gathering, professional services, and very-low signal-to-noise ratio (VL-SNR) applications. The core allows code and modulation changes on a block-by-block basis to fully support both Adaptive Coding Modulation (ACM) and Variable Coding Modulation (VCM).
The AHA4709E encoder core extends the functionality of the AHA4702 DVB-S2 family of cores by adding finer step MODCODs, new lower-order (BPSK) and higher-order (64, 128, 256 APSK) modulations, a medium 32K block size, and new bit interleaving patterns.
