Abstract: A communication scheme and system for converging a 5th generation (5G) communication system for supporting a data rate higher than that of a 4th generation (4G) system with an internet of things (IoT) technology are provided. The present disclosure is applicable to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, and security and safety-related services) based on the 5G communication technology and the IoT-related technology. The disclosure relates to a punctured polar code design method and apparatus and proposes optimal puncturing pattern and information set selection criteria for designing punctured polar codes.

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.

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.
