The impulsive noise is rejected using channel state information (CSI) and is performed in the frequency domain. A noise power estimate (furthermore referred to as a noise value) is measured for a single OFDM symbol and compared to a threshold value, which may be generated based on a short-term average of OFDM symbols not corrupted by impulsive noise or predicted based on a small number of previously measured OFDM symbols not corrupted by impulsive noise. If the noise estimate for the particular OFDM symbol exceeds the threshold value, the CSI for that symbol is derated (i.e. modified) to reduce the influence of the information from this symbol on the decoding process."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Impulsive noise rejection","description":"A method of rejecting impulsive noise in an OFDM receiver is described.
