摘要
Real-time deconvolution can be used as a powerful tool for the identification of linear systems in many areas. The availability of high speed VLSI convolvers/correlators opens new possibilities of dealing with this problem digitally. This paper analyzes the application of the frequency-domain Van-Cittert closed form as a deconvolution filter which can be implemented with such devices. The topics addressed include the choice of the optimum parameter values (scaling constant and expansion coefficient) in relation to the deconvolution bandwidth, and hence, deconvolution accuracy. It has been found that this technique shows a low sensitivity to the expansion coefficient value, making any repetitive optimization process unnecessary.
