    Abstract: The present disclosure provides a radar apparatus capable of suppressing a radar-to-radar in-band interference caused by a signal derived from another radar apparatus in a radar system in which a plurality of radar apparatuses share frequency resource to increase a frequency utilization efficiency. The radar apparatus includes: a receiver configured to acquire a received signal; a plurality of matched filters arranged in parallel to filter the receive signal, each corresponding to respective one of the plurality of radar apparatus to use a transmit signal of a corresponding radar apparatus as a reference signal; and a signal reconstructor configured to select a matched filter most adequate for an interference suppression based on outputs of the plurality of matched filters, subtract the reference signal of a selected matched filter at least partially from the receive signal, and reconstruct a desired echo signal to be used to determine a target.

    Abstract: The present disclosure relates to a method and apparatus for searching for a light-weight model through the replacement of a subnetwork of a trained neural network model. The method of searching for a light-weight model includes a preprocessing step of extracting a subnetwork from an original neural network model, constructing a mapping relation between the subnetwork and an alternative block corresponding to the subnetwork by extracting the alternative block from a pre-trained neural network model, and generating profiling information including performance information relating to the subnetwork and the alternative block, and a query processing step of receiving a query, extracting a constraint that is included in the query through query parsing, and generating the final model based on the constraint, the original neural network model, the alternative block, the mapping relation, and the profiling information.

    Abstract: The present invention relates to a method and apparatus for performing two dimension fast fourier transform for hologram processing. A method for processing a hologram according to an embodiment of the present disclosure may comprise: generating complex data by multiplying the digital image by a random phase value; performing inverse fast fourier transform (IFFT) processing on the complex data; generating pattern information by multiplying a result of the IFFT processing by a quadrant phase; and processing the hologram based on the pattern information. Here, the IFFT processing may comprise a IFFT core operation that performs row-base IFFT and column-base IFFT on the complex data, and a single shift IFFT operation that applies a predefined rule to a result of one or more of the row-based IFFT or the column-based IFFT.

    Abstract: Disclosed herein is an apparatus and method for synchronizing a block in a blockchain network. The apparatus synchronizes node information of existing participating nodes connected to a blockchain network by joining the blockchain network, determines synchronization target blocks by calculating the current section of a blockchain using an agreed-upon block received from the existing participating nodes, receives a block header of each section and the segment hash table of a snapshot that are verification data for verifying synchronization target data for the synchronization target blocks from participating nodes that are not connected as peers, among the existing participating nodes, generates a snapshot by receiving snapshot segments and the blocks of the current section, which are the synchronization target data, from participating nodes connected as peers, among the existing participating nodes, verifies the snapshot generated from the snapshot segments, and synchronizes the verified snapshot.
