10-Gbps forward error correction system for 120-GHz-band wireless transmission

We are developing elemental technologies for next-generation high-speed wireless links for transmitting program materials in live broadcasts. In particular, we are developing a 10-Gbps forward error correction (FEC) system for transmitting multiplexed HD-SDI wireless signals in the 120-GHz-band. The system can send error-free 10-Gbps data transmissions over a distance of 3 km. This paper describes FEC for 120-GHz-band wireless transmissions and the results of indoor and outdoor transmission experiments that measured the BER characteristics of transmission using 10-Gbps FEC systems.
