Research and Realization of Enhancing Bluetooth Baseband Based on Security and Error Correction Algorithm
基于安全与纠错算法的增强型蓝牙基带研究与实现

The frequency hopping (FH) and error correction algorithms of Bluetooth were analyzed and improved for the defects of security and anti jamming. The performance of FH sequences based on advanced encryption standard (AES) iterated block cipher was analyzed,and the results showed the sequences had good performance on uniformity,correlation, and security. An enhancing error correction mechanism(EECM) combining the forward error correction with interleaving was adopted for Bluetooth DM packets, and the simulation was carried out based on Gillbert-Elliott channel. hhe result showed the EECM could improve the anti-interference ability largely. The ASIC structures of FH sequences generator and EECM were proposed,and the realized results of these enhancing IPs were obtained by using low-power,low-cost VLSI design techniques. The performance of enhancing Bluetooth baseband was analyzed compared with the standard 131uctooth baseband. Finally, the Bluctooth system-on-chip was realized and tested by using platform-based design method.
