Abstract

This paper describes on evaluating performance of blind channel estimation methods to cancel the multipath interference from a severity of channel measurement. The proposed methods are considered in an optimal receiver behind the multiantenna system that provides by approaching a zero-forcing (ZF) and minimum mean square error (MMSE) based on the blind signal processing techniques. In this paper, we measured the 4 × 4 MIMO calibration kit with 2.45 GHz sleeve monopole array antennas and employed a vector network analyzer (VNA) to make of channel sounding. The measurement results after data processing is demonstrated by a realistic received signal and we point out how to evaluate the multipath interference with the proposed methods. For the MIMO multiantenna system, we guarantee that the proposed blind channel estimation methods helps to cancel the multipath fading channel and maintains an uncertainty of receiving signals in multiantenna system as perfectly.
