并行高斯干扰信道的噪声-干扰和速率容量

Noisy-interference Sum-rate Capacity of Parallel Gaussian Interference Channels

Xiaohu Shang, Biao Chen, Gerhard Kramer, H. Vincent Poor

摘要:

并行高斯干扰信道的和速率容量是通过在子信道上独立传输并在每个子信道中将干扰视为噪声来实现的,如果信道系数和功率约束满足一定的条件。该条件要求干扰是弱的,这是通常在例如,数字用户线传输。最优功率分配的特点是使用的和速率容量作为功率约束的函数。

英文摘要:

The sum-rate capacity of the parallel Gaussian interference channel is shown to be achieved by independent transmission across sub-channels and treating interference as noise in each sub-channel if the channel coefficients and power constraints satisfy a certain condition. The condition requires the interference to be weak, a situation commonly encountered in, e.g., digital subscriber line transmission. The optimal power allocation is characterized by using the concavity of sum-rate capacity as a function of the power constraints.
