Embodiment Construction

[0025] Certain terms are used throughout the specification and following claims to refer to particular components. Those of ordinary skill in the art will appreciate that manufacturers may refer to the same component by different terms. This description and the following claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The "comprising" mentioned throughout the specification and the following claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" here includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means.

Abstract

The invention discloses a wireless communication device and a control method thereof. The wireless communication device is used for being coupled with a multi-antenna module provided with a plurality of antennas. The wireless communication device comprises a switching circuit and a receiving module, wherein the switching circuit is used for changing the connection relations of the antennas according a switching signal in order to provide a plurality of antenna combinations through the multi-antenna module; the receiving module is coupled with the switching circuit; the receiving module comprises a signal intensity measuring circuit for measuring the signal intensity of wireless data packets received by the antenna combinations to generate a plurality of measuring results, and an antenna switching determination circuit for selecting a first comparison group comprising at least two antenna combinations from the antenna combinations at a training stage, allowing the receiving module to receive the wireless data packets, and determining a better antenna combination according to the measuring result of the first comparison group; and the receiving module enters the training stage according to a training enabling signal provided by a post-processing circuit, and enters a determination stage when the training enabling signal is ended by the post-processing circuit.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a wireless communication device for sending and receiving data packets with multiple antennas and its control method. Background technique [0002] With the advancement of technology, the use of wireless communication (wireless communication) systems is becoming more and more popular. However, for a wireless communication system, the transmission performance is easily affected by the environment, for example, the environment where the system is located has a serious channel effect, interference from other wireless communication systems or electronic equipment, or The shielding of buildings, etc., or the degree of signal attenuation caused by the orientation and position of the antenna, will affect the transmission and reception of the wireless system, such as the decrease of the signal-to-noise ratio (SNR), the increase of the PER, the low transmission rate, the data Pa...
