Abstract: Disclosed herein are an apparatus and method for providing FTN communication using transmit diversity. A transmission apparatus generates a signal to be output through diversity modulation. A diversity order of diversity modulation may be set based on an FTN parameter, such as a variable for adjusting sampling time or a symbol transmission speed. When the diversity order is set based on the FTN parameter, the FTN parameter and the diversity order may be set so as to satisfy a QoS required of the transmission apparatus, such as a transmission rate and a Bit Error Rate. Depending on the circumstances, the set FTN parameter and diversity order may be provided to a reception apparatus that is to receive the output signal.

Abstract: Disclosed herein are a method and apparatus for iterative interference cancellation and channel estimation in a system based on FTN communication including a pilot. Interference of a pilot symbol on a data symbol is estimated, and the estimated interference is eliminated from a sequence of data symbols. When demodulation and channel decoding are performed on the sequence of data symbols, interference between data symbols and interference of a data symbol on a pilot symbol are estimated. Such estimation is repeatedly performed, and as FTN interference is repeatedly estimated and eliminated, channel estimation performance is improved, and through the improved channel estimation performance, the reception performance of the entire system is improved.

Abstract: Disclosed herein are an apparatus and method for detecting a malicious script. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program is configured to extract token-type features, each of which corresponds to a lexical unit, and tree-node-type features of an abstract syntax tree from an input script, to train two learning models to respectively learn two pieces of learning data that are generated in consideration of features extracted respectively from the token-type features and the node-type features as having the highest frequency, and to detect whether the script is a malicious script based on the result of ensemble-based malicious script detection performed for the script, which is acquired using an ensemble detection model generated from the two learning models.
