FPGA Implementation of FD/TD-CMA Equalizers for 40-Gb/s THz Signal Transmission Over 200-m Link at 300 GHz
Three FD/TD-CMA equalizers were implemented based on FPGA for transmitting 40Gbit/s QPSK signals over a <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$200-m$</tex> THz link at 300 GHz. Compared to TD-CMA, FD-CMA can reduce hardware resources by more than 50%.
