Method for diversity antenna selection based on signal strength
A recently granted patent (Publication Number: US11848738B2) discloses a method and apparatus for signal reception using multiple antennas. The method involves receiving different portions of a signal using two antennas during different time periods, determining signal level differences between the received signal portions and threshold levels associated with each antenna, and selecting the antenna with the greater signal level difference for receiving subsequent signal portions. The threshold levels for each antenna are determined based on background signal measurements during non-transmission periods, with periodic updates to ensure optimal signal reception.
The networking apparatus described in the patent includes a receiving circuit, two antennas, a switch for antenna selection, and a signal processing circuit. This apparatus implements the method by determining signal level differences for received signal portions using each antenna, based on pre-defined threshold levels specific to each antenna. By selecting the antenna with the greater signal level difference, the apparatus ensures efficient signal reception. Additionally, the apparatus stores and updates threshold values based on background signal measurements, ensuring adaptability to changing signal conditions. The disclosed method and apparatus are particularly suited for signal formats compliant with the Zigbee protocol, offering a practical solution for optimizing signal reception in networking applications.
