摘要： This invention discloses a receiver and a signal compensation method therefor. An adaptive equalizer and a baseline wander compensator are provided on the front end of the receiver to improve the quality of output signals. The signal compensation method enables the adaptive equalizer to use a long T as its observation unit when the transmission cable is idle, and enables the baseline wander compensator for operation and controls both the adaptive equalizer and the baseline wander compensator to use a short T as its observation unit when the transmission cable is transmitting data signals. The disclosed adaptive equalizer can achieve its optimal processing effects, and the efficiency of the baseline wander compensator can be increased.

摘要： The present invention details a novel application of wireless networking and digital music technologies to achieve coordinated and synchronized music playback among peer listeners connected by wireless ad-hoc networks. Two or more listeners in local proximity allowed by short-range wireless transmission can participate and listen to the same song at the same time. Moreover, the present invention allows listeners in the transmission range to discover each other through profile matching. A high matching score may indicate similar preference or taste to a certain music style thereby easily locating mutual interests, which would not have been possible.
