ABSTRACT:
The diversity SCO digital audio technique (300) provides packet protection through statistical diversity by adding new audio modes (202, 204) that operate within a Bluetooth framework (200). Increased packet protection improves audio intelligibility and data transmission. The combination of a blind or signaled transmission of a redundant packet (202or204) in combination with a randomly faded frequency hop for each packet provide for enhanced reliability and link quality.
