APPARATUS AND METHOD FOR DETECTING RIPPLES CAUSED BY MULTIPATH PROPAGATION AND CONTROLLING RECEIVING ANTENNA AND TUNER |
摘要 |
<p>Improved signal reception is provided in a digital television signal received by identifying and mitigating multipath signal effects prior to demodulation and equalization. According to an exemplary embodiment, a digital television signal is received having multipath signal effects which cause a plurality of ripples in the received signal. The amplitude of at least one of the ripples and the frequency separation between at least two of the ripples are detected. At least one of an antenna and a tuner is controlled in dependence upon the detection. Signal demodulation and equalization operations may be performed after at least one of the antenna and the tuner is controlled.</p> |
