Apparatus for mapping and spreading data symbols in mobile communication systems |
摘要 |
The present invention discloses an apparatus for mapping and spreading data symbols in a mobile communication system which can improve efficiency of the system by performing data symbol mapping and spreading processes by using binary operations. The apparatus maps and spreads data symbols by using binary operations when quadrature phase shift keying modulation is performed in a mobile communication time division duplex mode. |
