Forward Error Correction

Today’s hottest commodity is bandwidth. At AHA, the goal is to help customers achieve higher data rates, increase bandwidth and ensure data integrity. As experts in coding technology, AHA offers a variety of hardware and IP core solutions based on the company’s patented technology including Low Density Parity Check Code (LDPC), Turbo Product Code (TPC), and Reed-Solomon (RS) technology. Whatever your application, AHA has the FEC solution.

Packet Recovery Accelerator
AHA's Packet Recovery Accelerator incorporates AHA's FEC Packet Recovery, so lost packets in a network can be recovered without need for retransmit.  This technology benefits any network appliances that may experience high packet loss due to network congestion, ensuring delivery with low latency and overhead.

AHA400PCIe 5.0 Gbps Packet Recovery Accelerator

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.
Product Description
AHA4704 15 Mbps LDPC Code Encoder/Decoder Core

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.

AHA4709D DVB-S2-X Compliant Decoder Core
AHA4709E DVB-S2-X Compliant Encoder Core
AHA4709L DVB-S2-X Compliant LLR Demapper Core
AHA4709S DVB-S2-X Compliant Symbol Mapper Core
AHA4709P DVB-S2-X Compliant Physical Layer Framing Core

DVB-S2 is the most accepted and widely spread standard in the satellite market. AHA has been offering DVB-S2 IP cores and integrated circuits since 2004. DVB-S2 uses powerful LDPC codes at rates from 0.25 to 0.9 and modulations QPSK to 32APSK that can be changed on-the-fly to support ACM and VCM.
