Serially concatenated BCH codes

Turbo Product Codes (TPCs)

Serially Concatenated BCH Codes

TPCs are serially concatenated BCH codes with row/column interleaving between the inner and outer code. This structure coupled with iterative soft-decision decoding results in error-correction performance close to the Shannon limit. TPCs are particularly powerful at high code rates.

A Pioneer in TPC Technology

Our TPC algorithms formed the backbone of AHA4540, the first commercially-available TPC ASIC. We have used TPCs as the FEC layer of the IPSTAR satellite communication system in Southeast Asia and several other communication platforms.
