| 摘要 |
The present invention is a two-channel (101, 102) wireless audio signal transmission system which uses frequency division multiplexing techniques to improve signal transmission and permit transmission of both channels over a common communication carrier (105). This invention is specifically adapted to meet the unique requirement of AC power line communication channels, although it can also be used with over-the-air RF communication channels. This invention permits the efficient transmission of high quality, low noise audio signals, as are desired for such applications as audio stereo system, home theater system and the like, without requiring dedicated wiring between the signal source or sources and the speaker devices. |
