AI Technical Summary

Problems solved by technology

However, this will cause certain side effects
For example, collision avoidance may involve scheduling of WLAN data packets (eg, Wireless Fidelity (Wi-Fi) data packets for short), resulting in a significant reduction in throughput
On the other hand, collision avoidance can also involve adaptive hopping of BT packets, resulting in significantly lower spectral efficiency
[0004] Thus, the solution direction for collision avoidance sacrifices throughput and / or spectral efficiency

Embodiment Construction

[0020] Certain words are used in the description and claims to refer to specific elements. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in functions of components as a criterion for distinguishing. The "including" mentioned in the entire specification and claims is an open term, so it should be interpreted as "including but not limited to." In addition, the term "coupling" here includes any direct and indirect electrical connection means. Therefore, if the text describes that the first device is coupled to the second device, it means that the first device can be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connecting means.

[0021] Please refer to figure 1 , figure 1 It is a schematic diagr...

Abstract

The invention provides a method for eliminating interference in a receiver (RX). The method includes: obtaining Bluetooth (BT) information and wireless local area network (Wireless LAN, WLAN) information by performing detection on at least one RX signal, wherein the RX signal is received through an antenna of the RX, and the RX signal includes components of both a BT signal and a WLAN signal that are respectively emitted from at least one transmitter (TX); and performing maximum likelihood (ML) joint detection on frequency representatives of the RX signal according to the BT information and the WLAN information and according to a predetermined library, in order to extract at least one of a reproduced version of the BT signal and a reproduced version of the WLAN signal. An associated apparatus is also provided.

Description

Technical field [0001] The present invention relates to a communication in an industrial, scientific and medical (Industrial, Scientific and Medical, hereinafter referred to as ISM) frequency band, and particularly relates to a method and device for eliminating interference in a receiver. Background technique [0002] Initially, the ISM frequency band was a frequency band reserved for radio frequency (Radio Frequency, hereinafter referred to as RF) applications for industrial, scientific, and medical purposes. Today, the ISM frequency band can also be used for license-free wireless communications. For the definition of the ISM frequency band, please refer to the radio regulations of the International Telecommunication Union Radiocommunication Sector (hereinafter referred to as ITU-R) for details. [0003] Those with ordinary knowledge in the field should understand that the ISM coexistence problem (that is, the coexistence interference problem in the same ISM frequency band) is a ...
