Abstract
A wireless audio system including a transmitter using multiple antenna diversity techniques for different signal types is provided. Multipath performance may be optimized, along with improved spectral efficiency of the system.
Claims20
A wireless audio transmitter, comprising:
- a plurality of antennas configured to each transmit an audio signal;
- an encoder configured to:
- (1) when utilizing a first transmission technique, receive and route a first symbol and a second symbol to each of a plurality of converters;
- and
- (2) when utilizing a second transmission technique:
- receive and encode the first symbol and the second symbol based on a first diversity technique;
- and
- route the encoded first symbol and the encoded second symbol to one or more subsets of the plurality of converters;
- a synchronization transformer configured to receive and transform a synchronization signal based on a second diversity technique;
- and
- the plurality of converters each in communication with the encoder, the synchronization transformer, and one of the plurality of antennas, wherein each of the plurality of converters is configured to:
- (1) when utilizing the first transmission technique, combine the first symbol, the second symbol, and the transformed synchronization signal into the audio signal to be transmitted on one of the plurality of antennas;
- and
- (2) when utilizing the second transmission technique, combine the encoded first symbol, the encoded second symbol, and the transformed synchronization signal into the audio signal to be transmitted on one of the plurality of antennas.

A method for wirelessly transmitting an audio signal using a wireless audio transmitter, the method comprising:
- receiving, at an encoder, a first symbol and a second symbol;
- when utilizing a first transmission technique, routing the first symbol and the second symbol to each of a plurality of converters, using the encoder;
- when utilizing a second transmission technique:
- encoding the first symbol and the second symbol based on a first diversity technique, using the encoder;
- and
- routing the encoded first symbol and the encoded second symbol to one or more subsets of the plurality of converters, using the encoder;
- receiving, at a synchronization transformer, a synchronization signal;
- transforming the synchronization signal based on a second diversity technique, using the synchronization transformer;
- when utilizing the first transmission technique, combining the first symbol, the second symbol, and the transformed synchronization signal into the audio signal to be transmitted on one of a plurality of antennas, using each of the plurality of converters;
- and
- when utilizing the second transmission technique, combining the encoded first symbol, the encoded second symbol, and the transformed synchronization signal into the audio signal to be transmitted on one of the plurality of antennas, using the one or more subsets of the plurality of converters.
