摘要： The invention relates to a repeater and a method for re-transmitting single frequency signals, in particular of the type used in single frequency signal repeaters for use in single frequency networks (SFNs) like digital video/audio broadcasting (DVB/DAB) networks. The estimation of echo feedback is derived from the measured power density spectrum with an inclusion of a variable phase shifter (57) in the signal path. Preferably, the phase shifter (57) is controlled by control means (56), which also set the adaptive filter (54) for feedback compensation, such that a signal coupled from the transmitter antenna back to the receiver antenna can substantially be cancelled out. The method according to the invention exhibits quick and stable regulation behavior and the re-transmitted signal does not suffer from degradation due to added interference. The quality of the signal at the transmitter antenna is improved even if dynamically changing feedback paths from the transmitter to the receiver antenna exist. The transmitter output power can be increased without increasing the risk of system instabilities, such as oscillations.

摘要： A method for detecting a-condition, where the signal level of an information signal, particularly of an orthogonal frequency division multiplexed (OFDM) digital information signal, exceeds at least one upper predetermined signal level and/or underruns at least one lower predetermined signal level for at least a predetermined time interval by feeding the information signal to at least one first mixer unit for producing a first signal and comparing said first signal to a at least a first level threshold value. Counting the number of incidences per time unit where said first signal is above or below said first level threshold value and comparing said number of incidences per time unit to a first frequency threshold value allows determination, if the condition is met or not. A device for detecting a condition, where the signal level of an information signal, particularly of an orthogonal frequency division multiplexed (OFDM) digital information signal, exceeds at least one upper predetermined signal level and/or underruns at least one lower predetermined signal level for at least a first predetermined time interval comprises at least one first mixer unit to which the information signal is fed for producing an output of a first signal, which is fed to at least one first comparator for comparing the first signal to a first level threshold value. Feeding the output of the first comparator to at least one counter for counting the number of incidences per time unit and comparing the output of the counter indicating the number of incidences per time unit to a first frequency threshold value using at least one second comparator allows determination, if the condition is met or not.
