在这项工作中，我们考虑一个二阶检测问题，其中秩p信号由一个未知的，但共同的，p维随机向量，然后通过未知的M × p矩阵在两个M元阵列的每一个接收。各通道的噪声是独立的，具有相同的方差。我们推导出广义似然比（GLR）测试这个问题时，噪声方差是已知的或未知的。由此产生的检测问题可以被称为双通道因子分析问题。
In this work, we consider a second-order detection problem where rank-p signals are structured by an unknown, but common, p-dimensional random vector and then received through unknown M × p matrices at each of two M-element arrays. The noises in each channel are independent with identical variances. We derive generalized likelihood ratio (GLR) tests for this problem when the noise variance is either known or unknown. The resulting detection problems may be phrased as two-channel factor analysis problems.
