Problems solved by technology

However, when the communication device uses the bad channel in the channel diagram for signal transmission test, if the communication quality of the bad channel is poor, the communication performance will be reduced
Therefore, if the communication device does not use a suitable mechanism to test and update the channel map, it will not only affect the communication performance, but even cause communication failure

Abstract

The invention provides a communication device with a selection capability of an intelligent frequency hopping channel. One of the embodiment of the communication device comprises a signal receiving and transmitting circuit, a timer and a control circuit; the signal receiving and transmitting circuit receives and transmits a frequency hopping signal according to at least one part of good channels in a channel map; the timer records communication time of the signal receiving and transmitting circuit; and the control circuit compares the communication time of the timer with a threshold value, and judges whether a signal transmission test is carried out by bad channels in the channel map or not, so as to update the channel map. Preferably, the control circuit sets the communication time of the timer to be one of a plurality of pre-set values according to a quantity of the good channels in the channel map.

Description

Technical field [0001] The invention relates to a communication device, in particular to a communication device with an intelligent frequency hopping channel selection capability. Background technique [0002] The convenience brought by wireless communication has made people use more and more wireless communication devices in their daily lives. However, some communication devices will communicate in certain frequency bands on a fixed basis, which will affect other communication devices that use the same frequency band. Therefore, adaptive frequency hopping (adaptive frequency hopping) technology is used in some communication systems to avoid or reduce the influence of interference signals in certain fixed frequency bands on signal transmission. For example, in the Bluetooth standard, adaptive frequency hopping technology is used to transmit voice, data, or control signals. [0003] Communication devices using adaptive frequency hopping technology need to have the ability to gener...
