本文概述了一种多址接入方案，其中交织是用户分离的唯一手段。作为码分多址的一种特殊形式，新方案继承了码分多址的许多优点，如动态信道共享、抑制小区间干扰、异步传输、小区规划容易、抗衰落能力强等。此外，它允许低成本的干扰消除技术适用于在多径信道中具有大量用户的系统。基于不等功率控制策略，已观察到接近理论极限的性能。
This article outlines a multiple access scheme in which interleaving is the only means of user separation. As a special form of CDMA, the new scheme inherits many advantages of CDMA, such as dynamic channel sharing, mitigation of cross-cell interference, asynchronous transmission, ease of cell planning, and robustness against fading. Furthermore, it allows a low-cost interference cancellation technique applicable to systems with large numbers of users in multipath channels. Performance close to theoretical limits has been observed based on an unequal power control Strategy.
