MULTI-CHANNEL WIRELESS SPEAKER SYSTEM USING MULTIPLEXED CHANNEL COMBINING AND FREQUENCY DIVERSITY

摘要

A multi-channel wireless speaker system using multiplexed channel combining and frequency diversity is described. The invention is directly applicable to the communication of audio signals between audio signal generators, such as home theater systems, stereo amplifiers, radio receivers, and other similar audio systems. This invention is adapted to provide multiple audio signals (211-217) on a single communication channel. It is specifically adapted to be used with RF wireless (207) and/or AC power line communication channels. This invention avoids the requirement for dedicated wiring connecting the audio signal source and the audio speakers. Moreover, this invention permits a large number of audio signals (211-217) to be separately modulated (201a-201n) and summed (204) on a single composite signal as well as a receiver able to demodulate and demux the composite into the many audio signals which are capable of connection to speakers.
