弱对称交叉链路蜂窝信道的干扰对齐和确定性容量

On Interference Alignment and the Deterministic Capacity for Cellular Channels with Weak Symmetric Cross Links

J. Buehler, G. Wunder

摘要:

在本文中,我们研究了使用线性确定性近似模型的蜂窝系统的上行链路,其中有两个用户发送到一个接收器,相互干扰的第三个发射机与第二个接收器通信。我们给出了一个可实现的编码方案,并证明了其最优性,即表征的容量区域。该方案是一种干扰对齐的形式,其利用两个用户小区的信道增益差。

英文摘要:

In this paper, we study the uplink of a cellular system using the linear deterministic approximation model, where there are two users transmitting to a receiver, mutually interfering with a third transmitter communicating with a second receiver. We give an achievable coding scheme and prove its optimality, i.e. characterize the capacity region. This scheme is a form of interference alignment which exploits the channel gain difference of the two-user cell.
