Forward Error Correction

Today’s hottest commodity is bandwidth. At AHA, the goal is to help customers achieve higher data rates, increase bandwidth and reduce system costs. 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), enhanced Turbo Product Code (eTPC), Turbo Product Code (TPC), and Reed-Solomon (RS) technology. Whatever your application, AHA has the FEC solution.

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 create a wide variety of LDPC cores to match specific data rate, latency and block size requirements.

Turbo Product Codes
AHA’s Turbo Product Codes (TPCs) family of integrated circuits and IP cores have set the standard for satellite communications. We offer a variety of products to match unique data rate and block size requirements.  With technology that approaches the theoretical limit of error correction,  AHA’s proprietary TPC technology reduces bandwidth strain — enabling higher performance through faster data rates and more efficient transmissions.

Reed-Solomon
AHA’s  Reed-Solomon (RS) Forward Error Correction integrated circuits are the technology that launched the company. RS is part of AHA’s legacy and an important component of its current success. Boasting the only commercially available RS integrated circuit, the AHA4013, AHA is the undisputed leader for RS technology. Whether your priorities are lowering costs or achieving higher data rates, AHA has the RS hardware and IP cores to meet your specifications.
