Abstract
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.
