    • 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.
    • 提出了一种通过无线电信道接收无线电信号的方法,该方法用于在接收广播信号失败的情况下保持时间同步。 该方法包括在接收到的无线信号的符号的用于时间同步的比较和已被存储在所述无线电接收器中的符号,误差值在Zeitsynchronisaiton的确定,过去误差值的平均值的计算中,时刻同步的校正到当前计算的误差值和在接收失败 围绕平均值的时间同步校正。 通过DAB,可以使用相位参考符号来确定时间同步的误差值。 本发明的方法允许在接收机中使用固定频率振荡器,因为通过本发明的方法改善了接收行为。
