Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication systems such as Long Term Evolution (LTE). A method for operating a receiver in a wireless communication system may include: receiving a signal from a transmitter; performing Integer Forcing (IF) equalization on the received signal; determining a log LikeLihood Ratio (LLR) value of each bit by using a posteriori probability of each bit for the signal determined based on an equalization matrix and a likelihood value for the signal; and decoding the signal by using the LLR value.

Abstract: A method and a device for transmitting a signal by using a polar code are provided. The method includes generating a first codeword by applying the polar code to an input signal, dividing the first codeword into a plurality of partial vectors, allocating a shaping bit to the input signal when at least one of the plurality of partial vectors does not satisfy a preset Hamming weight condition, generating a second codeword by applying the polar code to the input signal to which the shaping bit is allocated, and transmitting a signal based on the second codeword.

Abstract: A transmitter, a receiver and signal processing methods are provided. The transmitter includes: an encoder configured to perform encoding on an information word based on a parity check matrix to generate a codeword including a plurality of non-binary symbols; an interleaver configured to interleave the codeword; and as modulator configured to modulate the interleaved codeword to generate a plurality of modulation symbols. The interleaver is configured to interleave the codeword such that the modulator maps a predetermined non-binary symbol from among the plurality of non-binary symbols constituting the codeword to a predetermined position in a modulation symbol among the plurality of modulation symbols.

Abstract: The present disclosure relates to a pre-5t-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for operating a transmitting stage in a wireless communication system includes generating a signal by encoding an input bit sequence according to polar code determined from a linear code, and transmitting the signal to a receiving stage. The input bit sequence includes a second frozen bit which is determined based on a first frozen bit and an information bit. The first frozen bit and the information bit precede the second frozen bit in the input bit sequence.
