This paper presents a scheme applying the technique of Adaptive Frequency Hopping (AFH) to WPAN system in which works on the complex interference environment and the performances of the bit error rate (BER) for some WPAN systems that use AFH technique are analyzed.First
the background of WPAN systems and the typical interferences in WPAN environment are discussed.Then
the theoretic analysis of especially the BER characteristics of this scheme is given.Finally
the simulation of the cases of data rates commonly used in 1600 hops/s is performed taking 802.15.1 (Bluetooth) and 802.15.3 system as examples.The results show that the AFH technique improves the BER performance of the WPAN systems nearly 1~2 order of magnitudes when these systems work in the same frequency band within a small area.The result is also applicable for other WPAN systems using high-speed frequency hopping technique.
