研究了K用户单输入单输出符号间干扰(ISI)信道，假设信道系数是线性时不变的，具有有限长的冲激响应。本文的主要发现是，在发射机没有信道状态信息(CSIT)的情况下，只要期望的链路具有比干扰链路更长的冲激响应，和谱效率就可以与K成线性关系。这种线性增益是通过一种新的多载波通信方案实现的，我们称之为无干扰正交频分复用(IF-ofdm)。推导结果的一个主要含义是，在具有ISI的干扰信道中，跨每条链路的子载波的单独编码足以线性地增加K的和谱效率。仿真结果支持这一论断。
This paper considers a K-user single-input-single-output interference channel with inter-symbol interference (ISI), in which the channel coefficients are assumed to be linear time-invariant with finite-length impulse response. The primary finding of this paper is that, with no channel state information at a transmitter (CSIT), the sum-spectral efficiency can be made to scale linearly with K, provided that the desired links have longer impulse response than do the interfering links. This linear gain is achieved by a novel multi-carrier communication scheme which we call interference-free orthogonal frequency division multiplexing (IF-OFDM). A major implication of the derived results is that separate encoding across subcarriers per link is sufficient to linearly increase the sum-spectral efficiency with K in the interference channel with ISI. Simulation results support this claim.
