考虑了利用无线电传感器阵列以最小延迟检测随机无线源的存在。在每个传感器的模数转换仅限于读取模拟接收信号的符号的约束下，研究了该问题。我们将得到的数字信号处理任务以简单的形式表述为顺序假设检验。为了避免多元二进制数组数据难以处理的概率模型，采用了指数族内的简化模型表示和对数似然比近似。这种方法允许我们设计一个基于似然的序列检验，并根据Wald的经典论点分析它的分析性能。在卫星导航与同步系统无线频谱监测的背景下，我们研究了以平均样本数为特征的可实现处理时延与所使用的二进制传感器的函数关系。通过仿真验证了所讨论的低复杂度感知和决策技术的实际可行性和潜力。

英文摘要：
  Detecting the presence of a random wireless source with minimum latency utilizing an array of radio sensors is considered. The problem is studied under the constraint that the analog-to-digital conversion at each sensor is restricted to reading the sign of the analog received signal. We formulate the resulting digital signal processing task as a sequential hypothesis test in simple form. To circumvent the intractable probabilistic model of the multivariate binary array data, a reduced model representation within the exponential family in conjunction with a log-likelihood ratio approximation is employed. This approach allows us to design a likelihood-based sequential test and to analyze its analytic performance along Wald's classical arguments. In the context of wireless spectrum monitoring for satellite-based navigation and synchronization systems, we study the achievable processing latency, characterized by the average sample number, as a function of the binary sensors in use. The practical feasibility and potential of the discussed low-complexity sensing and decision-making technology is demonstrated via simulations.
