METHOD FOR GENERATING ADAPTIVE FREQUENCY HOPPING SEQUENCE FOR BLUETOOTH COMMUNICATION

摘要

PURPOSE: A method for generating an adaptive frequency hopping sequence for Bluetooth communication is provided to actively cope with various interfering signals environment by evaluating a channel in a Bluetooth, discriminating the evaluated channel, and generating an adaptive frequency hopping sequence on the basis of the channel evaluation result. CONSTITUTION: An original Bluetooth hopping sequence(HOP(K)) is generated(301). The generated hopping sequence is compared with data of a memory storing a link state classification result(303). If the hopping sequence can be compared with the link state classification result, it is determined which group the hopping sequence belongs to(305). If the hopping sequence is determined to belong to a defective channel(305), a sequence having an LQF(Link Quality Factor) which satisfies a threshold value(TLQF) is searched(307). If there is no sequence having the LQF which satisfies the threshold value(TLQF), a maximum value(LQFMAX) of the LQF is searched from an overall hopping sequences(310). A channel set satisfying the LQFMAX is set(311), one of the channel set is selected and registered for an adaptive frequency hopping sequence(312), and a channel group good for a transmission buffer is updated(313).
