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 interleavers 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 interfe-rence from other users.Simulation in AWGN and Rayleigh fading channel was performed to verify the feasibilityof the technology.
