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;
- a plurality of converters in communication with the plurality of antennas;
- an encoder configured to:
- receive and encode one or more symbols based on a first diversity technique;
- and
- route the encoded one or more symbols to one or more converters of the plurality of converters;
- and
- a synchronization transformer configured to receive and transform a synchronization signal based on a second diversity technique,
- wherein each of the plurality of converters is in communication with the encoder, the synchronization transformer, and a corresponding antenna of the plurality of antennas, and wherein each of the one or more converters is configured to:
- combine the encoded one or more symbols and the transformed synchronization signal to generate a combined audio signal for transmission via a corresponding one of the plurality of antennas.
7 more elements
A method comprising:
- encoding one or more symbols based on a first diversity technique;
- routing the encoded one or more symbols to one or more converters of a plurality of converters;
- transforming a synchronization signal based on a second diversity technique;
- combining, at each of the one or more converters, the encoded one or more symbols and the transformed synchronization signal to generate a combined signal;
- and
- transmitting, via a corresponding antenna of a plurality of antennas, the combined signal.
3 more elements
A non-transitory computer readable medium storing instructions that, when executed, cause:
- encoding, at a transmitter, one or more symbols based on a first diversity technique;
- routing the encoded one or more symbols to one or more converters of a plurality of converters;
- transforming a synchronization signal based on a second diversity technique;
- combining, at each of the one or more converters, the encoded one or more symbols and the transformed synchronization signal to generate a combined signal;
- and
- transmitting, via a corresponding antenna of a plurality of antennas, the combined signal.
