Patent ID: 8885738

Claim:
An apparatus for providing an output data signal based on a received television analog signal that includes a single carrier signal and a received television analog signal that includes a multiple carrier signal, the apparatus comprising: (a) a receiving section configured to convert each received television analog signal into an intermediate output signal and further configured to process each intermediate output signal that includes the single carrier signal and each intermediate output signal that includes the multiple carrier signal; (b) an equalizer section configured to: equalize the intermediate output signal in a frequency domain, wherein the frequency domain equalization is performed on each intermediate output signal that includes the single carrier signal and is performed on each intermediate output signal that includes the multiple carrier signal, add zero padding to at least one frame body that includes 3780 samples and is included in the single carrier signal and add zero padding to at least one frame body that includes 3780 samples and is included in the multiple carrier signal prior to employing each of a plurality of same Radix-2 fast Fourier transform (FFT) components to equalize the single carrier signal and the multiple carrier signal, wherein the zero padding extends a number of samples included in the at least one frame body to equal a power of two that is greater than the 3780 samples, and perform polynomial interpolation on the padded multiple carrier signal to reduce the number of samples to 3780 samples based on a polynomial resampling of a result of a complex division/conjugate multiplication performed on the padded multiple carrier signal; and (c) an output section that is operative to employ the equalized intermediate output signal to generate symbols at a 7.56 Msps rate as the output data signal.
