Abstract: A method for receiving data by a terminal in a wireless communication system according to the present document comprises: receiving a channel signal and a reference signal (RS) from a base station; and generating a sequence by filtering the RS, and decoding the channel signal on the basis of the generated sequence, wherein the filtering is zero forcing (ZF) filtering, and the decoding of the channel signal is a selection of one parameter from among parameter sets generated in accordance with a colored-noise machine learning process.

Abstract: Proposed is a method for a terminal to decode a signal. In particular, the method for a terminal to decode a signal comprises: a step for demodulating a first low density parity check (LDPC)-coded signal; and a step for decoding a second signal obtained from the first demodulated signal through a trained neural network. The second signal is obtained by using: an output sequence generated on the basis of the trained neural network; and a log likelihood ratio (LLR) sequence of the first signal.

Abstract: Proposed is a signal transmission method for a transmitting end performing visible light communication. The signal transmission method for a transmitting end performing visible light communication comprises: a step of modulating a signal; and a step of applying analog dimming control on the modulated signal and transmitting same. Meanwhile, the analog dimming control may include biasing of the modulated signal, and scaling of the modulated signal.

Abstract: The present specification provides a method for transmitting a signal in a wireless communication system. More specifically, the method performed by a transmission terminal comprises the steps of: generating at least one bit into a complex symbol by using a modulation scheme; mapping the complex symbol to subcarriers each having an even index or subcarriers each having an odd index among subcarriers of at least one configured resource block; performing IFFT on the subcarriers to which the complex symbol is mapped, in order to generate a time-continuous signal; performing a DC bias on the time-continuous signal; and transmitting the DC biased signal.
