Based on the time domain and frequency domain united single carrier modulation time division multiple access (TFU-SCM-TDMA) technology which is used in uplink of Bradio system, the interleave division multiple access (IDMA) is introduced into the uplink to make it support multiuser communication in the same slot simultaneously. It uses different inter-leavers to distinguish multiuser, and inserts training sequences at thetransmitting end to get the channel information between multiuser and base station respectively. The multiuser iterative decoding is adopted at receiving end to eliminate the interference from other users. Simulation in AWGN and Rayleigh fading channel was performed to verify the feasibilityof the technology.%基于BRadio系统上行采用的时频域联合单载波调制时分多址(TFU-SCM-TDMA)技术,将交织多址接入(IDMA)技术引入其中,同一时隙中可以支持多用户同时通信.该方式用不同的交织器区分不同用户,并在发送端插入训练序列以分别获得用户到基站的信道信息,在接收端采用多用户迭代译码消除其他用户的干扰.在AWGN和瑞利衰落信道下进行仿真,验证了所提方法的可行性.
