摘要

在经典的信息和通信理论中,高斯信道上的信道容量和可达速率,无论是恒定信道还是衰落信道,无论是单用户信道还是多用户信道,都被表征为用于传输信息的功率的函数。在实际的通信收发器中,为电子设备供电和完成所有所需的信号处理所需的相关电路功率通常不涉及容量表征。然而,为了实现通信系统的整体能源效率,通信方案的适应应以总功耗为基础。在本文中,我们在考虑总功率约束的情况下,描述了许多基本信道上可实现的最大速率。

Maximum Achievable Rates with Transmission and Circuit Total Power Constraints
In classical information and communication theory, channel capacity and achievable rate over Gaussian channels, whether for constant or fading channels and whether for single user or multiple users, are characterized as functions of the power that is used for the transmission of the information. The associated circuit power that is needed in real communication transceivers to power up the electronics and to do all required signal processing is typically not involved in the capacity characterization. However, to achieve global energy efficiency of the communication systems, the adaptation of the communication schemes should be based on total power consumption. In this paper, we characterize the maximum achievable rates over many fundamental channels taking total power constraints into considerations.
