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.

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 circuit 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 specification, AHA can easily create a custom LDPC core to match your specific data rate, latency and block size requirements.
