Abstract: The new DHx packets are adopted in Bluetooth 2.0+EDR specification. Without any error correction coding mechanism, it has poor anti-interference ability in the burst errors channel. To enhance the data transmission throughput and anti-interference ability efficiently, a method by introducing new packets with BCH codes and interleaving to the Bluetooth 2.0+EDR specification is proposed. The packet properties of new packets are deduced based on the packet definition of Bluetooth specification. An analytical model of the throughput in different burst error cases is presented under the Gillbert-Elliott(GE) channel, the throughput of different packets in different burst error cases are obtained. The simulation result shows that adding new packets with BCH codes and interleaving to Bluetooth 2.0+EDR specification can improve the anti-interference ability and the data transmission throughput increases more than 100% in the higher burst errors channel.
