SUPER-RESOLUTION BLIND CHANNEL MODELING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method of estimating a frequency response of a wideband channel and subsequently extracting a channel model when the measurement of only part of the wideband channel, specifically only measurement in a disjoint frequency subband is available.;SOLUTION: A propagation channel is reconstituted from measurement in the disjoint frequency subband of a wideband channel of interest. A delay in the subband is estimated at a high resolution of a multipath parameter on the basis of a sounding signal which is transmitted only in the subband, a channel impulse response of the subband is acquired on the basis of the delay, and proper software coupling arising from the result is used, thus extracting a channel estimation value which accurately interpolates a gap between the measured subbands, and the channel model.;COPYRIGHT: (C)2012,JPO&INPIT
