Custom coding, adaptive rate control, and distributed detection for Bluetooth
Matthew C. Valenti, Max Robert · 2003
Three strategies for improving the performance of point-to-point Bluetooth links are presented. All of the strategies are implemented on the host computer, and therefore no modification of the Bluetooth standard is necessary. The first strategy is custom error control coding, which is achieved by transporting BCH codewords within AUX1 packets. The second concept is adaptive rate control, which involves dynamically selecting the packet type that offers the best throughput for the current channel SNR. Finally, a distributed detection technique is proposed, whereby each packet is broadcast to a group of two or more receivers that are linked over a reliable backbone, and the packet is accepted if it is received correctly at any receiver in the group.
