Method for receiving radio signals via a radio channel
Abstract
The invention relates to a method for receiving radio signals via a radio channel. The inventive method is used for maintaining time synchronisation when radio signals are not received due to a failure. According to said method, symbols for time synchronisation in the received radio signals and a symbol which has been stored in the radio receiver are compared. Error values are determined during time synchronisation. Medial alligation of past error values is carried out. Time synchronisation is corrected by the currently calculated error value and by the mean value when reception does not take place. In a continuous duty with intermittent loading, a phase reference symbol can be used for determining the error value of time synchronisation. The inventive method allows for the use of a fixed frequency oscillator in the receiver because the reception performance is improved by the inventive method.
