Abstract: We demonstrate transmission of a 200-Gb/s superchannel over 3-km single-mode optical fiber (SMF) targeting intra-data center interconnect applications using a novel single-section ...
Abstract: A brief review of the principles and properties of F-QPSK (quadrature phase shift keying) modulation is given. Its spectral efficiency is compared with that of Gaussian minimum-shift keying ...
Block diagram of demodulator section: As you can see, I'm using a Costas Loop with a PI (Proportional-Integrator controller) to control the local oscillator The screenshot at the top shows an example ...
