2results about How to "Reduce packet error rate" patented technology

This invention provides a wireless communication link selection method and a half-duplex communication system for selecting multiple physical wireless communication links between a transmitter and a receiver in a half-duplex communication system. Both the transmitter and receiver are equipped with switching switches and antennas. The method includes: the transmitter and receiver synchronously and sequentially switching their respective antennas into working states according to their pre-stored switching switch timing sequences; when any transmitter antenna and any receiver antenna are simultaneously in working states, a wireless communication link is formed, and each wireless communication link is traversed at least once; during the transmission period of any wireless communication link, the receiver transmits unidirectional heartbeat packets or time-division bidirectional heartbeat packets with the transmitter through the current wireless communication link; the transmitter and / or receiver that receives the heartbeat packet selects the optimal wireless communication link from the multiple wireless communication links based on the signal strength and packet error rate during the heartbeat packet transmission process.

An embodiment provides a controller for a participant of a communication system, wherein the communication system performs wireless communication in a frequency band used for communication by multiple communication systems, wherein the controller is used to identify a channel access mode, wherein the channel access mode indicates a frequency hopping-based and / or time hopping-based occupancy of a frequency band that can be used for communication by the communication system, wherein the controller is designed to determine the channel access mode based on individual information of the communication system and based on a state of a digital sequence generator for generating a digital sequence or a number of the digital sequence.
