本文对时分多址（IDMA）系统进行了全面的研究。IDMA接收机的原则，为不同的调制和信道条件进行了概述。提出了一种基于密度演化技术的半解析方法来估计系统的误码率。它提供了一种快速和相对准确的方法来预测IDMA方案的性能。利用简单的卷积/重复码，对于涉及多达约100个用户的IDMA系统，观察到具有一个接收天线的3比特/码片的总吞吐量和具有两个接收天线的6比特/码片的总吞吐量。
This paper provides a comprehensive study of interleave-division multiple-access (IDMA) systems. The IDMA receiver principles for different modulation and channel conditions are outlined. A semi-analytical technique is developed based on the density evolution technique to estimate the bit-error-rate (BER) of the system. It provides a fast and relatively accurate method to predict the performance of the IDMA scheme. With simple convolutional/repetition codes, overall throughputs of 3 bits/chip with one receive antenna and 6 bits/chip with two receive antennas are observed for IDMA systems involving as many as about 100 users.
