Problems solved by technology

However, since the 2.4GHz frequency band is commonly used by various wireless devices, such as Bluetooth devices, home wireless phones and WLAN devices, when a WLAN wireless device operates in the 2.4GHz frequency band and uses a 40MHz transmission bandwidth, it will be vulnerable to other wireless devices using the same frequency band. The signal interference of wireless devices in the frequency band affects the transmission performance
In this case, if the interference problem cannot be effectively dealt with, the channel traffic of the WLAN wireless device using the 40MHz transmission bandwidth for signal transmission will be greatly reduced, and its channel traffic may even be lower than that of the channel using the 20MHz transmission bandwidth for signal transmission flow

Abstract

A wireless device and an interference judging method thereof. The wireless device operates in a first bandwidth mode, and according to the received at least one radio frequency signal, counts a first channel clear assessment (CCA) associated with a primary channel, a second CCA amount associated with a primary channel , an overall CCA quantity associated with at least one of the major channel and the minor channel, and a false alarm quantity. Then, if the second CCA number exceeds the sum of the first CCA number and a deviation, the wireless device determines that it is in an interference state, and judges the interference state according to a ratio of the overall CCA number and the false alarm number It belongs to one of a first interference type and a second interference type.

Description

technical field [0001] The invention relates to a wireless device and an interference judging method thereof. In particular, it refers to a wireless device capable of judging whether the wireless device is in the interference state, and then determining whether the interference state belongs to the first interference type or the first interference type and the interference judging method thereof. Background technique [0002] With the development of wireless local area network (wireless local area network; WLAN), in order to meet the demand of high throughput (throughput; TP), the Institute of Electrical and Electronic Engineers (Institute of Electrical and Electronic Engineers; IEEE) has formulated the latest wireless network standard 802.11n. In addition to supporting the 20 megahertz (MHz) transmission bandwidth of the original 802.11abg specification, the 802.11n specification also supports a 40MHz transmission bandwidth, that is, the 802.11n specification uses two adjac...
