能源效率已经成为无线通信的一个重要方面，无论是在经济上还是在环境上。本文采用多种译码策略对下行AWGN信道的能量效率进行了研究。系统的总体能效以每焦耳位数度量为基础，其中能效等值线用于根据系统要求定位最佳工作点。我们的新方法使用线性功率模型来定义基站的总功率消耗，包括电路和处理功率以及放大器效率，并确保在满足其他系统目标的同时获得最佳的能效值，例如服务质量和速率公平性。
Energy efficiency has become an important aspect of wireless communication, both economically and environmentally. This letter investigates the energy efficiency of downlink AWGN channels by employing multiple decoding policies. The overall energy efficiency of the system is based on the bits-per-joule metric, where energy efficiency contours are used to locate the optimal operating points based on the system requirements. Our novel approach uses a linear power model to define the total power consumed at the base station, encompassing the circuit and processing power, and amplifier efficiency, and ensures that the best energy efficiency value can be achieved whilst satisfying other system targets such as QoS and rate-fairness.
