Abstract
An apparatus for demodulating a digital video broadcast signal comprising data modulated on a multiplicity of spaced carrier frequencies. A transform device may analyze the digital broadcast signal to provide a series of symbol values for each of the multiplicity of carrier frequencies. An automatic frequency control device may control the frequency of the series of symbol values in dependence on a common phase error signal from the series of symbol values. First and second common phase error correction (CPE) devices may receive common phase error signals, for correcting the signal values from the transform device. A channel equalization device may compensate for communication channel impairments for receiving directly the phase error corrected signals from the first CPE device.
