反应式和主动式继电保护选择策略之间的基本关系
Fundamental Relations Between Reactive and Proactive Relay-Selection Strategies
摘要：
在协作解码转发（DF）中继网络中广泛应用的两种中继选择策略，即反应式中继选择（RRS）和主动式中继选择（PRS），通常被看作是独立的，分别进行研究。本文从第一性原理即中继选择准则出发，证明了RRS和PRS在端到端中断概率方面是等价的。另一方面，RRS被证明是优于PRS的端到端的符号出错率。然后，以中继节点和目的地均受到同频干扰和加性高斯白噪声影响的一般DF中继系统为例，明确说明了上述中断等效性。这些基本关系提供了直观而有见地的性能基准比较这两个继电器选择策略的各种应用。
英文摘要：
Two major relay-selection strategies widely applied in cooperative decode-and-forward (DF) relaying networks, namely, reactive relay selection (RRS) and proactive relay selection (PRS), are generally looked upon as independent and studied separately. In this paper, RRS and PRS are proven to be equivalent with respect to the end-to-end outage probability from the first principle, i.e. their respective relay-selection criteria. On the other hand, RRS is shown to be superior to PRS with respect to the end-to-end symbol error rate. Afterwards, a case study of a general DF relaying system, subject to co-channel interferences and additive white Gaussian noise at both the relaying nodes and the destination, is performed to explicitly illustrate the aforementioned outage equivalence. These fundamental relations provide intuitive yet insightful performance benchmarks for comparing various applications of these two relay-selection strategies.
