Abstract：A novel blind deconvolution algorithm based on autocorrelation function of band-pass signal is proposed, only single input is required. The input data is transformed to its complex baseband through demodulation and decimation processing. For the baseband signal, a blind deconvolution algorithm is deduced, which minimizes the squared sum of the real part of the signal autocorrelation function over a region excluding a region near the zero delay point. Computer simulations show that the algorithm works well. It is widely applicable for bandpass Gaussian as well as non-Gaussian signals.
