    Abstract: A multi-solution based radio system is provided. A radio system adaptively selects a solution to be used in a communication method based on a quality of service (QoS). The radio system estimates a QoS, such as by using information about at least one of a channel state, a signal state, a performance using a current solution, a complexity using a current solution, and a power consumption of a terminal with respect to a current solution. When the estimated QoS does not satisfy a predetermined condition, the radio system changes a current solution to an alternative solution or changes a parameter value applied to the current solution using feedback information.

    Abstract: Provided is a method and apparatus for lattice reduction with reduced computational complexity. The apparatus and method include calculating an R matrix using sorted QR decomposition, and conducting an R-value test using an R-value based on diagonal elements of the R matrix and a threshold value. The R matrix is an upper triangular matrix. The apparatus and method further execute a loop comprising a size reduction and a conditional update of a basis vector corresponding to a column element of the R matrix in response to the R-value being greater than or equal to the threshold value. The apparatus and method conduct another R-value test based on the R matrix comprising the updated basis vector in response to the basis vector being updated.

    Abstract: A soft demapping apparatus and method thereof includes a pre-processing unit to pre-process a reception signal obtained from a symbol representing bits. A candidate selection unit selects two candidates from among constellation points included in a constellation for each of the bits. A distance calculation unit calculates a Euclidean distance between the reception signal and the two candidates. A log-likelihood ratio (LLR) calculation unit calculates an LLR with respect to the bits based on the Euclidean distance between the reception signal and the two candidates.

    Abstract: Disclosed are a communication method 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 disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety related services, and the like) on the basis of 5G communication technology and IoT-related technologies. According to various embodiments of the disclosure, a method for authenticating a smart key of an electronic device comprises the steps of: transmitting an authentication request in a predetermined cycle; receiving authentication responses from a smart key device; determining whether there is a relay attack on the basis of the interval of the received authentication responses; and authenticating the smart key device when it is determined that there is no relay attack. However, the disclosure is not delimited to the embodiment above, and other embodiments are possible.
