A method of detecting a broadcast OFDM signal, the broadcast OFDM signal comprising a plurality of symbols, each symbol comprising a guard frame comprising a cyclic prefix, and a data portion, the method comprising the steps of: receiving a plurality of samples from a broadcast receiver, the number of samples corresponding with the length of at least two OFDM symbols; performing a sliding correlation on the received plurality of samples to identify a peak of correlation between the samples, the sliding correlation occurring a number of samples apart corresponding with a number of samples in the data portion of an OFDM symbol; correcting a phase of the received samples using the identified peak in correlation to generate a phase corrected signal; performing a first correlation comprising correlating a plurality of samples from a first region of the phase corrected signal with a plurality of samples in a second region of the phase corrected signal, the first region corresponding with a guard frame of an OFDM symbol, the second region corresponding with a portion of the data portion of an OFDM symbol corresponding with the guard frame; performing a second correlation comprising correlating a plurality of samples from a third region of the phase corrected signal with a plurality of samples in a fourth region of the phase corrected signal, the third region corresponding with a portion of a data portion of an OFDM symbol, and the fourth region corresponding with a portion of a data portion of a subsequent OFDM symbol; detecting a broadcast OFDM signal in the plurality of samples from the broadcast receiver based on the first and second correlations by: generating a first metric of the samples comprising the first correlation by counting a number of received correlating samples in the phase corrected signal that lie in the negative complex plane; generating a second metric of the samples comprising the second correlation by measuring the angular distribution of received correlating samples in the phase corrected signal and measuring a deviation of the angular distribution of received correlating samples in the phase corrected signal across all quadrants of a complex plane; and comparing the first and second metrics with a threshold value. receiving a plurality of samples from a broadcast receiver, the number of samples corresponding with the length of at least two OFDM symbols; performing a sliding correlation on the received plurality of samples to identify a peak of correlation between the samples, the sliding correlation occurring a number of samples apart corresponding with a number of samples in the data portion of an OFDM symbol; correcting a phase of the received samples using the identified peak in correlation to generate a phase corrected signal; performing a first correlation comprising correlating a plurality of samples from a first region of the phase corrected signal with a plurality of samples in a second region of the phase corrected signal, the first region corresponding with a guard frame of an OFDM symbol, the second region corresponding with a portion of the data portion of an OFDM symbol corresponding with the guard frame; performing a second correlation comprising correlating a plurality of samples from a third region of the phase corrected signal with a plurality of samples in a fourth region of the phase corrected signal, the third region corresponding with a portion of a data portion of an OFDM symbol, and the fourth region corresponding with a portion of a data portion of a subsequent OFDM symbol; detecting a broadcast OFDM signal in the plurality of samples from the broadcast receiver based on the first and second correlations by: generating a first metric of the samples comprising the first correlation by counting a number of received correlating samples in the phase corrected signal that lie in the negative complex plane; generating a second metric of the samples comprising the second correlation by measuring the angular distribution of received correlating samples in the phase corrected signal and measuring a deviation of the angular distribution of received correlating samples in the phase corrected signal across all quadrants of a complex plane; and comparing the first and second metrics with a threshold value. generating a first metric of the samples comprising the first correlation by counting a number of received correlating samples in the phase corrected signal that lie in the negative complex plane; generating a second metric of the samples comprising the second correlation by measuring the angular distribution of received correlating samples in the phase corrected signal and measuring a deviation of the angular distribution of received correlating samples in the phase corrected signal across all quadrants of a complex plane; and comparing the first and second metrics with a threshold value.
