METHOD FOR GENERATING TRANSMISSION SYMBOLS IN TRANSMITTER AND THE TRANSMITTER

摘要

PURPOSE: A method for generating a transmission symbol in a transmitting device, and a transmitting device thereof are provided to obtain a improved transmission symbol having a higher encoding gain. CONSTITUTION: A preprocessing function supply unit(110) generates a preprocessing function which satisfies a design condition for obtaining single symbol decoding complex and a design condition for maximum space diversity and a maximum transmission rate. A permutation function designing unit(120) provides a designed permutation function in a preprocessing function providing unit after designing a permutation function which maximizes a minimum CGD(Encoding Gain Distance). A preprocessing unit(130) outputs an encoding unit(140) by generating transmission symbol form a circle symbol according to a final preprocessing function. The encoding unit transmits the preprocessed symbols by encoding the symbols.
