Abstract: A fluorescence microscopy metrology system includes an optical system configured to generate first light and second light having different wavelengths, a microscope body configured to irradiate a sample, coated with a fluorescent material, with the first light and the second light received from the optical system, and to receive fluorescence reflected from the sample, an image detection device configured to detect a fluorescence image corresponding to the received fluorescence, and a nanostructure analysis device configured to measure line edge roughness (LER) from the detected fluorescence image, to analyze power spectral density (PSD), or to detect a nanoparticle defect.

Abstract: A receiving apparatus includes: a first decoder configured to decode a signal transmitted through a first layer from a layered division multiplexing (LDM) signal using a parity check matrix to generate low density parity check (LDPC) information word bits and parity bits; an encoder configured to encode the LDPC information word bits, generated by decoding the signal transmitted through the first layer, using the parity check matrix to generate parity bits corresponding only to preset columns in the parity check matrix; and a second decoder configured to decode a signal obtained by removing, from the LDM signal, a signal corresponding to the LDPC information word bits generated by decoding the signal transmitted through the first layer, the parity bits generated by the encoder, and the parity bits generated by the first decoder except the parity bits generated by the encoder, thereby to generate information word bits transmitted through a second layer.
