ABSTRACT:
The channel frequency of a digital radiotelephone is coarse tuned utilizing the phase information of the symbols. According to the invention the phase change between the measured phases of one or more received symbols (d) and the previous symbol (e) is detected, the phase change being compared with allowed phase changes. Based on this a decision (g) is made concerning the phase of the transmitted symbol, the phase error (f.sub.err) or difference between the decision (g) and the measured phase change (d) is generated, and on this basis the channel frequency is adjusted.
