ZHAO Xian-jing1,ZHENG Bao-yu1,QIAN Xiao-cong1,FU Hong-liang2(1.Institute of Signal and Information Processing of Nanjing University of Posts and Telecomm.,Nanjing 210003,China;2.Depart.of Communication and Information Engineering of Nanjing University of Posts and Telecomm.,Nanjing 210003,China)  
A novel cooperative diversity system combined with distributed space-time block code and multi-carrier code division multiple access(DSTBC-MC-CDMA) techniques was proposed,which works well in multi-user wireless net-works with single-antenna users in frequency selective fading channels.And an analytical model was established to simulate the symbol decoding error between interusers,based on which,a close form expression for theoretical bit error rate(BER) performance of the system was derived.Then the simulation was done to versify the analytic results above,and the simulation also shows that the BER performance of DSTBC-MC-CDMA outgoes non-cooperative MC-CDMA with distinctive gains.Furthermore,the simulation results coincide with the theoretical results well.
