Interference Channels with Source Cooperation

Vinod M. Prabhakaran, Pramod Viswanath

摘要:

合作管理干扰的作用-无线信道的一个基本特征-研究通过研究两个用户的高斯干扰信道的源节点可以在全双工发送和接收。该信道的总容量在恒定比特数的间隙内获得。所使用的编码方案建立在Han和Kobayashi(1981)的叠加方案上,用于无合作的两用户干扰信道。新的上限和能力也来自。同样的编码方案,以获得对称的两个用户高斯干扰信道的和容量与无噪声反馈在一个恒定的间隙。

英文摘要:

The role of cooperation in managing interference - a fundamental feature of the wireless channel - is investigated by studying the two-user Gaussian interference channel where the source nodes can both transmit and receive in full-duplex. The sum-capacity of this channel is obtained within a gap of a constant number of bits. The coding scheme used builds up on the superposition scheme of Han and Kobayashi (1981) for the two-user interference channel without cooperation. New upperbounds on the sum-capacity are also derived. The same coding scheme is shown to obtain the sum-capacity of the symmetric two-user Gaussian interference channel with noiseless feedback within a constant gap.
