摘　　要：交织分多址接入(IDMA)技术是第四代移动通信的关键技术之一,它具有卓越的多用户通信性能和较低的接收复杂度,并且是一种具有较高容量的无线通信技术。仿真结果表明:在Eb/N0较低的时候,IDMA系统多用户性能随着迭代次数增加可以很好的向单用户性能趋近。同时,当用户数达到50以上的时候,系统也保持了这种良好的性能。Interleave division multiple access （IDMA） is one of key technologies in the fourth generation of mobile telecommunication. It has predominant multi-user communication performance and low-complexity receiver, and is one of high throughputs wireless communication technologies. Simulation results show that, with the increase of iteration, the multi-user performance can approximate to single-user performance when Eb/N0 is relatively low. Meanwhile, the system can keep good performance when it contains more than 50 users.
