METHOD FOR DETERMINING IMPULSIVE INTERFERENCE APPLICABLE TO ORTHOGONAL FREQUENCY DIVISION MULTIPLE ACCESS SIGNAL RECEIVER AND RECEIVER THEREOF

摘要

A method for determining impulsive interference applicable to an orthogonal frequency division multiple access (OFDMA) signal receiver is provided. The receiving method includes calculating a subcarrier noise of a first symbol, calculating a subcarrier noise of a second symbol, calculating a first ratio of the subcarrier noise of the first symbol to the subcarrier noise of the second symbol, determining whether the ratio is greater than a first threshold, and recognizing that the first symbol suffers from impulsive interference when the first ratio is greater than the first threshold.

1. A method for determining impulsive interference applicable to an orthogonal frequency division multiple access (OFDMA) signal receiver, comprising:
calculating a subcarrier noise of a first symbol; calculating a subcarrier noise of a second symbol; calculating a first ratio of the subcarrier noise of the first symbol to the subcarrier noise of the second symbol; determining whether the first ratio is greater than a predetermined first threshold; and recognizing that the first symbol suffers from the impulsive interference when the first ratio is greater than the first threshold.
