Low Density Parity Check Codes
AHA's newest FEC IP offerings are Low Density Parity Check Code (LDPC) cores. AHA's IP provides an economical solution to obtaining greater coding gain and placing communications links closer to the Shannon Limit for Bit-Error-Rate (BER) performance.
| Product | Description |
|---|---|
| AHA4701 | 30 Mbits/sec LDPC Encoder/Decoder Core |
| AHA4702 | DVB-S2 Compliant LDPC/BCH Forward Error Correction Core |
Turbo Product Codes
AHA's Turbo Product Codes (TPCs) are simply the best price/performance Forward Error Correction integrated circuits available anywhere. With technology that approaches the theoretical limit of error correction, no commercially available chip comes closer to providing error-free data transmission than AHA's TPCs. AHA's proprietary technology reduces bandwidth strain -- enabling higher performance through faster data rates and more efficient transmissions.

Reed-Solomon
AHA set the standard for performance with its Reed-Solomon (RS) Forward Error Correction integrated circuits. This is the technology that launched the company's first product. RS is part of AHA's legacy and an important component of its current success. Boasting the fastest commercially available RS device (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.
