摘要

本文导出了单边相关随机Gram矩阵的逆矩的封闭表达式。这个问题主要是由信号处理和无线通信中的应用引起的，在这些应用中，评估这个量是一个重要的问题。例如，这是最佳线性无偏估计器的情况，其中平均估计误差对应于随机Gram矩阵的第一个逆矩。

Exact closed-form expression for the inverse moments of one-sided correlated Gram matrices

In this paper, we derive a closed-form expression for the inverse moments of one sided-correlated random Gram matrices. Such a question is mainly motivated by applications in signal processing and wireless communications for which evaluating this quantity is a question of major interest. This is for instance the case of the best linear unbiased estimator, in which the average estimation error corresponds to the first inverse moment of a random Gram matrix.
