Performance analysis of beamformers using generalized loading of the covariance matrix in the presence of random steering vector errors [PDF]
Robust adaptive beamforming is a key issue in array applications where there exist uncertainties about the steering vector of interest. Diagonal loading is one of the most popular techniques to improve robustness.

Robust adaptive beamforming for interference suppression based on SNR [PDF]
Robust adaptive beamforming (RAB) can be used to suppress interference signals while retaining the desired signals received by a sensor array. However, desired signal self-cancellation and model mismatch can affect RAB performance. In this paper, a novel

Maximum Likelihood Estimation of the Interference-Plus-Noise Cross Power Spectral Density Matrix for Own Voice Retrieval [PDF]
In headset and hearing aid applications, it is of interest to retrieve the user's own voice in a noisy environment, e.g. for telephony applications. To do so, the cross-power spectral density (CPSD) of the interference-plus-noise is required.

Local large deviation principle, large deviation principle and information theory for the signal-to-interference-plus-noise ratio graph models [PDF]
Given devices space $D$, an intensity measure $λm\in(0,\infty)$, a transition kernel $Q$ from the space $D$ to positive real numbers $(0,\infty,$ a path-loss function (which depends on the Euclidean distance between the devices and a positive constant $α$), we define a Marked Poisson Point process (MPPP).
