Abstract

A method of estimating the spatio-temporal channel parameter is proposed. Using a mechanically rotating antenna which has a narrow beam width, we show how to estimate the distribution of the incoming signal in the directions of the angle and delay. With the proposed method, the estimation problem is represented as a deconvolution problem which can be converted as a matrix equation with constraints. We also show the results of the proposed method tested with field data
