- W2010507975 abstract "The DFT-based channel estimation method is widely used in OFDM systems due to a good balance between computation complexity and performance. But this DFT-based method encounters degradation of performance caused by the energy leakage from non-sample locations of the multipath timing. To alleviate the leakage effect, a channel estimation method by adding virtual channel frequency response (VCFR) was proposed in [7]. However, this VCFR method cannot adapt to the complicated situations of the uplink reception for LTE Physical Uplink Shared Channel(PUSCH). Owing to the above issue, an improved method which adopts a novel frequency window function and a new noise reduction strategy is presented. The superiority of the proposed method over other VCFR channel estimation methods is verified in performance and flexibility to various multipath fading channels." @default.
