Disclosed are: a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety related services, and the like) on the basis of 5G communication technology and IoT-related technology.

Data interleaving device and method in wireless communication system using polar code

The disclosed techniques allow for transmitting a signal stream from a sender to a receiver in an environment including multiple senders and receivers. The technique for the sender decomposes a data stream from the sender into multiple substreams, encodes a substream by a codeword, further superimposes multiple codewords to form a signal stream in an asynchronous manner, and transmits the signal stream to the receiver. A codeword can span over multiple blocks. The receiver receives a first codeword stream from a first sender, receives a second codeword stream from a second sender, the two codeword streams may be received at the same time as one signal, and decodes the first codeword stream and second codeword stream over a sliding window of multiple blocks.

Methods and apparatus for coding for interference network

The disclosure is related to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE). A method for operating a first device in a wireless communication system includes receiving information bits and distributed cyclic redundancy check (CRC) bits from a second device, and decoding the information bits and the distributed CRC bits, wherein the information bits and the distributed CRC bits are decoded by using a successive cancellation list decoding scheme that uses a parity check matrix determined based on a linear combination of rows of a predetermined parity check matrix, or by using a successive cancellation flip decoding scheme that uses the distributed CRC bits.

Apparatus and method for decoding using cyclic redundancy check in wireless communication system

The present disclosure relates to a pre-5-Generation (5G) or 5G communication system for supporting higher data rates beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE). A performance of the existing sliding-window superposition coding (SWSC) is degraded when a wireless channel state is changed due to a large scale fading and a small scale fading. In addition, the performance of the existing SWSC is degraded when channel state information at a receiver is different from that of the real channel. To resolve these problems, a transmitter applies an accurate data transmission rate suitable for a channel state. Therefore, a receiver applies an adaptive SWSC and to reduce a block error rate (BLER) and a hybrid automatic repeat request (HARQ) overhead of the receiver. In addition, to resolve wireless channel state change due to large and small scale fading, the transmitter may use the adaptive transmission method.
