Abstract  Abstract

PURPOSE: An apparatus and a method for complicated re-transmission in a mobile communication system are provided to retransmit efficiently data by generating sub-codes for optimum code combination. CONSTITUTION: A maximum code rate and a minimum code rate of a transmitter are determined by a transmission data rate of a system(401). The number of sub-code is obtained by using the maximum code rate, the minimum code rate, and a predetermined mathematical expression(403). A variable m is initialized(405). The number of symbol selected within a punching matrix is determined(407). The number of component encoder in a turbo encoder is compared with a difference between the symbol number selected within a punched matrix and the column number of the punching matrix(409). Information symbols are selected from the punching matrix and the remaining symbols are selected according to a predetermined type(411). The remaining symbols are selected from the first parity symbols and the second parity symbols by using a predetermined mathematical expression if the first type(413). The remaining symbols are selected from the first parity symbols and the second parity symbols by using a predetermined mathematical expression if the second type(415).
