METHOD FOR ENCODING TURBO CODE AND TRANSMITTER THEREOF

摘要

PURPOSE: A method for encoding turbo codes is provided to use an error correction technique by using turbo codes for low speed data and to improve the function for high speed data. CONSTITUTION: The method for encoding turbo codes comprises: a step to encode by inserting a predetermined data which are informed to a receiving terminal to original data. The step to encode comprises a step to delete the inserted bits wherein the inserted bits are PN code or a random bits. Bits inserted again instead of the bits deleted at a turbo decoder are bigger than the original data. A transmitter comprises a PN code generator(210) to generate PN codes, a multiplexer(200) to multiplexing the random bits and the original data and a turbo encoder(230) to encode the multiplexed signal.
