Scattered pilot symbols are adaptively tracked by applying a weighted summation function over the received symbols to get a “snapshot” of the pilot symbols. Channel impulse response and frequency response can then be applied to the snapshot for channel estimation. The channel estimation is then used for interpolating one or more data symbols. Furthermore, the path information of the channel impulse response can help to optimize the OFDM window position."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatuses for channel estimation of OFDM systems to combat multipath fading","description":"Methods for channel estimation for OFDM schemes are provided to combat multipath fading.
