The Application of BICM for the DS/CDMA System

NIU Kai,WU Wei ling,GAO Lu,YANG Hong yan(Beijing University of Posts and Telecommunications,Beijing 100876,China)  
A novel scheme constructing BICM(Bit Interleaved Coded Modulation) on the dual orthogonal sequences set was proposed in this paper.We derived the upper limit bound of the BER(Bit Error Rate) about the new approach.The method allows an efficient combination of punctured convolutional codes ,multiphase modulation ,interleaving and spreading spectrum.It is verified that the proposed system is superior to the conventional error coding schemes by approximately 2 4dB over a Rayleigh channel according to the theoretic analysis and computer simulation.In addtion,the paper shows that such scheme can provide high diversity order in the fast fading channel.Generally speaking,this scheme is very appropriate to the multi code transmission in the 3G mobile telecommunications systems.
