摘要：The broadcast mode of the different ones set by the international standardsfor digital audio broadcasting (DAB) according to a coded orthogonal frequency divisionmultiplexing scheme (COEFDM) may be automatically detected in a receiver through adetection routine. Many of the calculation modules required by the automatic modedetection system of the invention are already present in a receiver and can be exploitedfor performing the digital signal processing that leads to an automatic recognition of thebroadcast mode of the station on which the receiver is tuned.
