Method for blindly estimating OFDM modulation parameters

摘要

The method involves processing a set of demodulation requests of orthogonal frequency division multiplexing (OFDM) signal by using a set of respective values of a temporal modulation parameter. A kurtosis cost function representing entropy of the demodulated signal is calculated for each demodulation request. The parameter is estimated as a value of the parameter minimizing the cost function. The signal is demodulated in baseband using a demodulation frequency and sampled at a frequency higher than Nyquist frequency for obtaining a sequence of samples.
