Abstract:
1. A receiving unit for mobile radio transmission, comprising: a channel estimator for determining channel coefficients h a frequency estimation unit connected to said channel estimator, said frequency estimation unit determining a sequence of phase differences p(k) between received data symbols x(k) and frequency-error-free data symbols y(k) derived from a training sequence and determining a frequency shift Δω of the received data symbols x(k) from the sequence of phase differences p(k), said frequency estimation unit performing in a case where a sequence value of the sequence of phase differences p(k) deviates from a mean value p a frequency correction unit for correcting a phase of the received data symbols x(k) in dependence on the frequency shift Δω resulting in phase-corrected data symbols {overscore (x)}(k), said frequency correction unit connected to said frequency estimation unit; and a channel equalizer for equalizing the phase-corrected data symbols {overscore (x)}(k) using the channel coefficients h
