Problems solved by technology
Such an architecture not only has high hardware cost, but also increases the size of the device, which is not an ideal solution.
Moreover, the channel environment of the wireless signal may change at any time. If the change of the channel environment cannot be reflected immediately, the receiving quality and transmission speed of the wireless communication circuit will be reduced.

Embodiment Construction
[0020] Embodiments of the present invention will be described below in conjunction with related figures. In these drawings, the same reference numerals indicate the same or similar elements or process steps.
[0021] Certain terms are used in the specification and subsequent claims to refer to particular elements. Those skilled in the art should understand that the same elements may be called by different names. This specification and subsequent patent applications do not use the difference in name as a way to distinguish components, but use the difference in function of components as a basis for differentiation. The "comprising" mentioned throughout the specification and the subsequent claims is an open term, so it should be interpreted as "including but not limited to...". In addition, the term "coupled" herein includes any direct and indirect connection means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device ...

The invention provides a wireless communication circuit supporting an antenna diversity mechanism, which is used for controlling a switching circuit in a wireless communication device with a plurality of antennae, and comprises a transmit-receive circuit for receiving and transmitting network packets, a control module for controlling the switching circuit to switch the transmit-receive circuit among the antennae to allow the transmit-receive circuit to receive a preface section of the first network packet, and a receiving intensity detection unit for measuring receiving intensity values of the antennae in respective receiving periods respectively when the transmit-receive circuit receives the preface section, wherein if the receiving intensity values of the antennae are less than a preset threshold, the control module selects the antenna with the maximum receiving intensity value as a target antenna and controls the switching circuit to couple the transmit-receive circuit to the selected target antenna and allow the transmit-receive circuit to receive the rest, including a header section and a data bearing section, in the first network packet through the target antenna.
Description
technical field [0001] The invention relates to a wireless communication circuit, in particular to a wireless communication circuit supporting an antenna diversity mechanism. Background technique [0002] In a wireless communication system, the signal transmission effect of the wireless communication circuit is affected by the channel effect of the environment, and is often reduced by the direction and position of the antenna. [0003] Although the architecture using a single antenna has lower hardware costs and simpler control of signal transmission and reception, it often reduces signal transmission quality and data transmission rate due to poor antenna reception. [0004] When a known wireless communication circuit adopts a multi-antenna architecture to improve signal transmission quality, multiple sets of receiving circuits need to be provided to separately process signals received by different antennas. Such an architecture not only has high hardware cost, but also inc...
