Space modulation techniques (SMTs) have emerged as a family of multiple-input multiple-output (MIMO) transmitter designs that require a maximum of a single RF-chain. SMTs have been analyzed in the context of cost, power, and error performance in past studies and have shown to exert favorable advantages over traditional implementations such as spatial multiplexing (SMX). However, given future application requirements, analysis of the hardware also in the context of reliability becomes essential. In this work, an SMT hardware reliability analysis framework is devised using two quantitative analysis tools consisting of reliability block diagrams (RBDs) and Markov Chains. In addition, a comparative study using commercial component failure rates is performed to analyze how SMTs compare to each other.

空间调制技术的可靠性分析框架

空间调制技术 (SMT) 已成为多输入多输出 (MIMO) 发射器设计系列，需要最多单个 RF 链。在过去的研究中，SMT 已经在成本、功耗和错误性能方面进行了分析，并且显示出比空间复用 (SMX) 等传统实现更有利的优势。然而，考虑到未来的应用要求，在可靠性的背景下对硬件进行分析变得必不可少。在这项工作中，使用由可靠性框图 (RBD) 和马尔可夫链组成的两种定量分析工具设计了 SMT 硬件可靠性分析框架。此外，还使用商业组件故障率进行了比较研究，以分析 SMT 之间的比较。
