2 × 2干涉网络的和率

On the Sum Rate of a 2 x 2 Interference Network

Murali Sridhar, Srikrishna Bhashyam

摘要:

在M × N干扰网络中,有M个发射机和N个接收机,每个发射机具有用于接收机的2^N-1个可能的非空子集中的每一个的独立消息。我们考虑了具有6个可能消息的2 × 2干扰网络,其中2 × 2干扰信道和X信道分别是仅用2个和4个消息得到的特殊情况。从一个类似于Han-Kobayashi区域的可达速率区域出发,我们得到了一个可达和速率。对于高斯干扰网络,我们确定6个消息中的哪一个足以在低、混合和强干扰条件下使该速率区域内的总速率最大化。据观察,在几种情况下,2个消息就足够了。

英文摘要:

In an M x N interference network, there are M transmitters and N receivers with each transmitter having independent messages for each of the 2^N -1 possible non-empty subsets of the receivers. We consider the 2 x 2 interference network with 6 possible messages, of which the 2 x 2 interference channel and X channel are special cases obtained by using only 2 and 4 messages respectively. Starting from an achievable rate region similar to the Han-Kobayashi region, we obtain an achievable sum rate. For the Gaussian interference network, we determine which of the 6 messages are sufficient for maximizing the sum rate within this rate region for the low, mixed, and strong interference conditions. It is observed that 2 messages are sufficient in several cases.
