A Study on Application Effect of Delay Spread Estimation Method based on Level Crossing Rate to Ordering Cost Reduction Method in MU-MIMO-OFDM THP

Abstract (in Japanese) (See Japanese page) 
(in English) Broadband mobile wireless systems suffer from frequency selective fading due to multipath, which motivates us to
establish the method for easily estimating frequency selectivities. In this context, delay spread can be estimated by averaging
the impulse responses obtained from frequency responses using IFFT processing, which unfortunately requires a large amount
of computational effort. In this report, we propose the delay spread estimation method using level crossing rate. Moreover, the
proposed method is applied to the ordering cost reduction method for MU-MIMO-OFDM THP to verify the effectiveness of
the proposed approach.
