Impact of the Propagation Channel on Reception Quality of the DAB Signal,DM demodulator play a decisive role. And subcarrier levels are determined by individual path levels and relative delays between them in multipath wireless channel. It is clearly presented by the phasor representation of the signal paths in the baseband channel. The general rule is demonstrated by specific examples.
