    Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond the 4G communication system such as LTE. A decoding method using a polar code according to an embodiment of the present disclosure comprises the steps of: determining a first function for decoding input bits and a second function, which is independent from a log likelihood ratio (LLR) value of a previous input bit by the first function; and decoding the input bits in parallel using the first function and the second function. Also, the method comprises the steps of: determining an internal frozen bit using at least one input frozen bit which has a predetermined value of a predetermined position from among the input bits; and determining LLR values for layer bits sequentially from the higher layers of N layers.

    Abstract: A 5th-generation (5G) or pre-5G communication system which is to support a higher data transfer rate beyond a 4G communication system such as a long term evolution (LTE) is provided. The method for transmitting a downlink signal by a base station in a wireless communication system supporting non-orthogonal multiple access (NOMA) includes the steps of selecting a pair of terminals including one short-distance terminal and at least one long-distance terminal which will share an identical downlink transmission resource, generating a superimposed signal in which a signal for the short-distance terminal and a signal for the long-distance terminal are superimposed on one another, generating information necessary for cancelling the signal of the long-distance terminal from the superimposed signal, transmitting the generated information necessary for cancelling the signal of the long-distance terminal to the short-distance terminal, and transmitting the generated superimposed signal to the pair of terminals.

    Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as a long term evolution (LTE). A method for transmitting a signal in a signal transmitting apparatus in a communication system supporting a bit-interleaved coded modulation with iterative decoding (BICM-ID) scheme is provided. The method includes performing an outer encoding operation; performing an interleaving operation on the outer code corresponding to an interleaving scheme which is based on a preset generation matrix to generate an interleaved signal; performing an inner encoding operation; performing a modulating operation; and transmitting the modulated signal, wherein the generation matrix is generated by applying at least one of a preset column permutation rule and a preset row permutation rule to a generation matrix for a quasi-cyclic (QC) interleaver.
