Apparatus and method for generating codes in a communication system |
摘要 |
Disclosed is an apparatus and method for generating a QCTC (Quasi-Complementary Turbo Code) considering a characteristic of a turbo code in a packet communication system or a communication system using an ARQ (Automatic Repeat reQuest) scheme by segmenting a length N of the QCTC into a predetermined number of sections, determining SPIDs (Sub-code Packet Identifications) corresponding to the segmented sections, and specifying one of the SPIDs allocated for initial transmission of the sub-code; calculating a number of remaining symbols represented by N-Fs, where N is a length of the QCTC and Fs is a starting symbol position of the sub-code of the QCTC; determining a last symbol position Ls of the sub-code by comparing the number of the remaining symbols with a length of the sub-code; and sequentially transmitting symbols of the sub-code from the starting symbol position Fs to the last symbol position Ls.
