摘要

提出了一种分析AF中继网络的能量效率和误码率的新方法。在该网络中，信号源通过平坦衰落信道将信号传输到一组中间中继节点，中间中继节点对信号进行放大，然后通过其他平坦衰落信道将信号转发到目的地。在考虑中继位置的情况下，提出了一种考虑频谱效率(SE)的平衡方案。这种EE和SE之间的平衡是通过最小化功耗来实现的。在此基础上，分析了该平衡的BER，并推导了BER与EE之间的关系。通过数值模拟验证了所有解析表达式的正确性。

The effect of energy efficiency and spectrum efficiency on bit error rate for unidirectional relay networks

A new method to analyze Energy Efficiency (EE) verse Bit Error Rate (BER) in AF relay networks is presented in this paper. In this network, the source transmits signals through flat fading channels to a set of intermediate relay nodes which amplify signals and then forwards them to the destination through other flat fading channels. The proposed EE is derived in a balanced scheme with Spectrum Efficiency (SE), when relay location is considered. Such a balance between EE and SE is achieved by minimizing power consumption. Furthermore, the BER for this balance is analyzed and the relationship between BER and EE is derived. All analytical expressions are validated numerically by simulation.
