Gain adjusting method of wireless communication

Abstract

The invention discloses a gain adjusting method of wireless communication. The method is executed by a wireless transceiver, and an embodiment of the method comprises the following steps: acquiring atleast one transmission state parameter of a wireless connection object; deciding an appropriate power gain according to at least one transmission state parameter; setting a standby power gain of a radio frequency circuit as the condition that the appropriate power gain achieves a period of time, or during this period, setting the standby power gain of the radio frequency circuit as the appropriate power gain until a package is transmitted or received; and setting the standby power gain of the radio frequency circuit as the initial power gain when achieving at this period of time if the package is not transmitted or received during this period.

Description

technical field [0001] The invention relates to a gain adjustment method, in particular to a wireless communication gain adjustment method. Background technique [0002] As far as the packet form design of the wireless communication system is concerned, in order to achieve packet detection, signal synchronization, channel detection, etc., a preamble is added to the front end of the packet. In the process of demodulating a packet at a receiving end, once the receiving end finds that the field in the packet is illegal, or there is a cyclic redundancy check error (Cyclic RedundancyCheck error; CRC error), parity check error (parity check error) and other situations occur, the receiving end will think that this packet is not the packet that the receiving end wants, and will regard the packet as a false alarm (false alarm), at this time the receiving end will stop decoding the packet Tune in while waiting for the next packet to come in. [0003] In today's wireless local-area n...

Problems solved by technology

Some interference is very similar to the packet preamble of WLAN. Such interference will cause a wireless receiver to detect falsely and generate false alarms. Therefore, the current technology can make the wireless receiver adjust the initial power gain of a radio frequency circuit to avoid false alarms. However, the current technique is to lower the initial power gain of the radio frequency circuit so that the wireless receiver will not react or be overly sensitive to most interferences, but this may also prevent the wireless receiver from detecting normal packets , or make the wireless receiver unable to receive normal packets smoothly
