标题： On the Probability of Erasure for MIMO-OFDM

摘要： 检测有效信号的存在是电信接收机的一项重要任务。当由于噪声和衰落，接收机无法检测到有效信号时，这种情况被称为擦除。本文研究了用于多输入多输出（MIMO）系统的正交频分复用（OFDM）信号的擦除概率计算问题。理论结果通过计算机仿真得到了验证。由于能够减轻由频率选择性衰落信道引起的码间干扰（ISI），OFDM 被广泛应用于当今的无线通信系统中。MIMO 系统提供了空间复用的优势，从而提高了比特率，这是像 5G 及更高级别最近无线标准的主要需求。 显示英文摘要

摘要： Detecting the presence of a valid signal is an important task of a telecommunication receiver. When the receiver is unable to detect the presence of a valid signal, due to noise and fading, it is referred to as an erasure. This work deals with the probability of erasure computation for orthogonal frequency division multiplexed (OFDM) signals used by multiple input multiple output (MIMO) systems. The theoretical results are validated by computer simulations. OFDM is widely used in present day wireless communication systems due to its ability to mitigate intersymbol interference (ISI) caused by frequency selective fading channels. MIMO systems offer the advantage of spatial multiplexing, resulting in increased bit-rate, which is the main requirement of the recent wireless standards like 5G and beyond.
