Abstract
A Digital Terrestrial Multimedia Broadcasting (DTMB)-based carrier mode detection system includes first and second TPS decoders, first and second carrier calculators and a determinator. The first and second TPS decoders respectively receive Ninput signals to thereby produce the corresponding Nmask signals and to respectively perform an absolute operation on the corresponding Nmask signals to accordingly select a maximum result as first and second absolute maximum mask signals for output. The first and second carrier calculators respectively receive Ninput signals and produce first and second absolute summation carrier signals. The determinator is based on the first absolute maximum mask signal, the first absolute summation carrier signal, the second absolute maximum mask signal and the second absolute summation carrier signal to accordingly determine that the carrier mode is of a multi- or single-carrier mode.
