Claim 4:
5. The method for estimating dense multipath parameters by means of multipolarized broadband extended array responses according to claim 1, further comprising: estimating parameters including an initial phase, an amplitude, and an cross-polarization ratio, which is specifically as follows:
building an array response by using the estimated angle and delay parameters; obtaining a third matrix containing the cross-polarization ratio, the amplitude in each of the snapshots, and the initial phase of each polarization combination by using a least square method; calculating an argument for the third matrix, to obtain initial phases of horizontal and vertical polarization combinations of all sub-paths; calculating the cross-polarization ratio by using a relationship between each column of an obtained matrix and the cross-polarization ratio; and finally, estimating amplitude information of each of the sub-paths in the different snapshots by using the least square method.
