The Coding Techniques of Error Correction in Bluetooth
Zhao Liang · 2001
Bluetooth is a new type of short ranged wireless communication technology developed in recent years,the role of which is to take the place of cables and to connect mobile equipment such as handsets, portable PCS together with fixed equipment such as printers computers and so on.Bluetooth has manyadvantages such as high transmission rate and easy operation for networking.However,the interference environment is very complesx for indoor wireless communications,especially when Bluetooth operates at the same frequency range of a Microwave oven.Therefore,a very important question is to increase the ability of anti interference and to decrease the bit error rate.Obviously,some error correction coding techniques must be used to solve this problem.In this paper,we first introduce the principle of Bluetooth briefly.Then describe the link structure and packet formats.Finally we discuss and analyze in emphasis the error correction technique employed in Bluetooth.
