In some cases, measured cross-spectral matrices (CSM's) from a microphone array will be contaminated by severe incoherent noise signals in the individual channels. A typical example is flow noise when measuring in a wind tunnel. Assuming stationary signals and performing long-time averaging, the ...
In microphone array techniques the cross spectral matrix is used to localize acoustic sources. In this paper Daniell's method is revisited to average the cross spectral matrix of the sensor signals in the frequency domain. It is shown that this method leads to similar results as an averaging ...

The diagonal matrix \(W = E\left[ {uu^{\prime}|X} \right]\) has \(i\)th diagonal element \(w_{ii}\), which is an unknown function of Xi \(X_{i}\) alone: \(w_{ii} = {\text{var}} \left( {\mu_{i} |X_{i} } \right)\). The FGLS estimator; $$\hat{\beta }...
