Embodiment Construction

[0035] [Example of Wireless Interference Scanning Method for Adaptive Frequency Hopping]

[0036] Please refer to image 3 , image 3 It is a flowchart of a wireless interference scanning method for adaptive frequency hopping provided by an embodiment of the present invention. First, in step S310, monitor the overall signal strength of the broadband. Then, in step S320, it is judged whether the total signal strength of the broadband is greater than a critical value. The wide frequency band may include an Industrial Scientific Medical Band. For example, a Bluetooth device utilizes a frequency band around 2.4G, but the present invention is not limited thereto. The wide frequency band may also be, for example, a frequency band around 5 GHz specified in 802.11a, or other frequency bands, and the present invention does not limit the range and frequency of the frequency band. When the total signal strength of the broadband is greater than the threshold value (eg negative 35dBm),...

Abstract

The present disclosure provides a wireless interference scanning method and device for adaptive frequency hopping. The wireless interference scanning method comprise detecting the overall signal magnitude over a wide-band; determining whether the overall signal magnitude over the wide-band is larger than a threshold; sequentially detecting a plurality of channels in the wide-band to determine whether there is an interference signal in the channels when the overall signal magnitude over the wide-band is larger than the threshold; and redetecting the overall signal magnitude over the wide-band for determining whether the overall signal magnitude over the wide-band is larger than the threshold when the overall signal magnitude over the wide-band is not larger than the threshold.

Description

technical field [0001] The present invention relates to an adaptive frequency hopping technology, and in particular to a wireless interference scanning method and a wireless interference scanning device for adaptive frequency hopping. Background technique [0002] Please refer to figure 1 , figure 1 is a schematic diagram of a conventional wireless receiver. The antenna 101 of the radio receiver receives the wireless signal and transmits it to the low-noise amplifier 102. The mixer 103 mixes the local oscillating signal LO with the output signal of the low-noise amplifier 102 and outputs it to the filter 104. The filtered signal is output to the The variable gain amplifier 105 amplifies the signal, and the analog-to-digital converter (ADC) 106 converts the amplified signal into a digital signal and transmits it to the base frequency circuit 107 for processing. However, when there are multiple wireless communication devices, wireless signals may interfere with each other. ...
