A lightweight two-stage convolutional (deep) neural network (CNN) based modulation format identification (MFI) scheme is proposed and demonstrated for the polarization domain multiplexing (PDM) fiber communication system with probabilistically shaped (PS) formats. The tested on a PDM at symbol rate of 28 GBaud. Six formats (of 3 bit/symbol PS-16QAM, PS-32QAM, PS-64QAM, 4 PS-32QAM 5 PS-64QAM) along six standard (BPSK, QPSK, 8PSK three uniformly (US) QAM: US-16QAM, US-32QAM US-64QAM) are...
This letter proposes a multiresolution technique to address the high computational cost in remote sensing image registration. The scale-invariant feature transform is applied detect keypoints and descriptors, then, global information combined with descriptors utilized establish keypoint mappings. Keypoints are first classified according their octaves. Then, lowest resolution, of largest octave mapped information, giving an initial affine transformation <inline-formula...
We propose an accurate and nondata-aided chromatic dispersion (CD) estimation method involving the use of cross-correlation function two heterodyne detection signals for coherent optical communication systems. Simulations are implemented to verify feasibility proposed 28-GBaud systems with different modulation formats. The results show that has high accuracy measuring CD good robustness against laser phase noise, amplified spontaneous emission nonlinear impairments.
