摘要：

We describe an adaptive cross-spectral blind deconvolution method, cross-TEA, for the case where data is available from several sensors. Unlike ordinary cross-spectra, higher order cross-spectra are separable, and we use this fact to identify and deconvolve each system. We tested cross-TEA on four-channel QAM signals and compared the results to TEA, an autospectral method.
