Low Density Parity Check Codes |
AHA’s most powerful FEC offerings are based on Low Density Parity Check Code (LDPC) codes. AHA’s LDPC IP cores and LDPC integrated circuits provides an optimal solution to obtaining greater coding gain and placing communications links closer to the Shannon Limit for Bit-Error-Rate (BER) performance than any other FEC technology. In addition to our standard LDPC offerings based on the DVB-S2/DVB-S2X specification, AHA can easily create a custom LDPC core to match your specific data rate, latency and block size requirements. |

DVB-S2X (LDPC) |
DVB-S2X is the extension of the popular DVB-S2 satellite standard. Improvements including additional codes, higher modulations (64/128/256APSK) and smaller roll-off factors improve the efficiency by 51% over DVB-S2. |
