    Abstract: The present disclosure a method of operating user equipment (UE) in a wireless communication system, the method comprising: identifying layer information that is applied to a neural polar code; generating, based on the identified layer information, transmission data by encoding data that is input into the neural polar code; and transmitting the transmission data to a base station, wherein, based on polar code transformation, the neural polar code generates the transmission data by performing encoding, based on the polar code transformation, from an initial layer of the data to a first layer according to the identified layer information and by performing encoding through a neural network-based autoencoder after the first layer until the transmission data is generated.

    Abstract: A broadcast signal transmitter includes a first bit interleaver to bit interleave core layer data of at least one core layer Physical Layer Pipe (PLP) for a core layer; a second bit interleaver to bit interleave enhanced layer data of at least one enhanced layer PLP for an enhanced layer; an injection level controller to control power ratio between the bit-interleaved core layer data and the bit-interleaved enhanced layer data; a combiner to combine the core layer data and the enhanced layer data which the power ratio is controlled and to output Layered Division Multiplexing (LDM) data; a power normalizer to normalize power of the LDM data; a time interleaver to perform time-interleaving on the LDM data which the power is normalized; a framer to generate a signal frame comprising a preamble and the time-interleaved LDM data; and a modulator to perform Orthogonal Frequency Division Multiplexing modulation on the signal frame.

    Abstract: Disclosed are a method for dividing a carrying block of a Low Density Parity Check (LDPC) code and an apparatus therefor. The method for dividing a LDPC code of the present disclosure can obtain a high throughput by using a limited size of shifting network. Moreover, it is possible to prevent degradation in performance due to a minimum size of code block by performing shortening for a large size of code block while minimizing the number of code blocks. Furthermore, in selection of a minimum size of code block, since a minimum size of code block is selected on the basis of shortening for a relatively large size of code block, it is possible to increase the size of the minimum size of code block.
