<p>An array has Ne1 array elements for receiving a plurality of communication signals from different sources. A noise power estimator at each array element receives a signal and estimates the noise power by collecting NS data samples, forming a covariance matrix of the NS data samples based on a model order estimate, computing the eigenvalue decomposition of the covariance matrix and ranking eigenvalues from the minimum to the maximum for the determining the noise power of the received signal at the respective array element. A pencil-based blind source separation (BSS) processor receives the signals and noise estimates from each array element and noise power estimator and removes the noise.</p> |
