本文提供了一项关于交流多访问（IDMA）系统的全面研究。概述了不同调制条件的IDMA接收器原理。基于密度演化技术开发了一种半分析技术，以估计系统的比特率（BER）。它提供了一种快速且相对准确的方法来预测IDMA方案的性能。使用简单的卷积/重复代码，可以观察到IDMA系统的3位/芯片的总体吞吐量，带有一个接收天线和6位带有两个接收天线的芯片，涉及多达100个用户。
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.
