Abstract

The present invention discloses a transmission method and apparatus for a wireless communication system. The data transmission apparatus includes an encoder capable of encoding input data to generate first coded bits and second coded bits; a channel interleaver capable of interleaving said first coded bits and said second coded bits, to generate first interleaved coded bits and second interleaved coded bits; a partially swap unit capable of partially swapping said first interleaved coded bits to generate partially swapped first interleaved coded bits, and combining said partially swapped said first interleaved coded bits and said second interleaved coded bits to generate processed bits; a modulator capable of mapping said processed bits to modulation symbols in a predetermined modulation scheme; and a transmitter capable of transmitting the modulation symbols. Related methods are also disclosed.
