Blind Deconvolution for Underwater Acoustic Multipath Signal
A new algorithm based on autocorrelation function of band-limited single input for blind deconvolution of underwater multipath signals is proposed. In this algorithm, received signal spectrum is moved to around zero frequency first, and then passed through a LPF (Lowpass Filter) to generate a corresponding baseband complex signal after decimation. We deduce a LMS iterative algorithm for the complex blind deconvolution by minimizing the squared summation of the real part of the autocorrelation function over a region excluding the zero delay point. This algorithm is widely applicable no matter how the band-limited signal is Gaussian or not.
