摘要： A method by which a transmitting end operates in a wireless communication system comprises the steps of: performing sparse coding on information so as to have sparsity of which the number of non-zero symbols is K; configuring a codebook by including a code for spreading for each user; spreading the coded information by using one or more codes in the codebook; and transmitting a channel by overlapping the spread information. Therefore, even if the number of encoded symbols increases, the number of symbols actually having a value is very sparsely configured such that the complexity of a transmitter and a receiver does not increase, and thus restoration performance improves.

摘要： A method of receiving a signal by a receiver in a mobile communication system is provided. The method includes: receiving a reference signal from a transmitter; determining first channel information based on the received reference signal; receiving a data signal based on the first channel information; and determining second channel information based on the received data signal and the first channel information. Iterative channel estimation is performed to reduce channel estimation errors by determining errors of signals received from a turbo decoding unit and using symbol information as pilots even in subcarriers where the pilot signals are not transmitted, and to increase the accuracy of LLR calculation through an iteration process such as a detection and decoding process in comparison with the conventional technology, thereby increasing the reception performance of the turbo decoding unit and improving communication efficiency.
