FEC (Forward Error Correction)

Advanced Physical Layer Technologies

Our expertise in advanced physical layer technologies including Forward Error Correction (FEC) along with an array of in-house development makes us a one-stop FEC shop. Developments include a diversified portfolio of software, DSP, FPGA, and ASIC implementations of FEC for modems in several satellite, mobile, and optical communication systems.  

Advanced FEC Cores for Optical Communications

We have developed and implemented proven FEC modules that are necessary to achieve 100 Gbps throughput. FEC technologies include high gain turbo product code (TPC), low density parity check (LDPC), and Bose-Chaudhuri-Hocquenghem (BCH). Our products include IP cores for FPGAs and ASICs.

Viasat 66200 SDFEC (Soft Decision Forward Error Correction) is a family of turbo product code (TPC) designed for use in 200 Gbps communications applications. With either 7% or 20% overhead, TPCs are the optimum FEC for high data rate, high coding gain applications where low latency and high net equivalent coding gain (NECG) are desired.
