Embodiment Construction

[0025] The steps that the wireless radio frequency receiver sensitivity fast detection method according to the present invention comprises are: setting the detection range, making the packet error rate estimation range corresponding to the received power in the detection range include the target packet error rate; narrowing the detection range by a search mechanism and The number of packets sent when detecting the packet error rate is selected through the packet number setting mechanism; the received power is detected as the sensitivity of the wireless radio frequency receiver by using the estimated packet error rate that satisfies certain conditions and approaches the target packet error rate. The mechanism for setting the detection range, the search mechanism, and the number of packets to be sent will be described in detail below through multiple embodiments.

[0026] 1. Set the detection range

Abstract

The invention relates to a method and device for rapidly detecting the sensitivity of a wireless radio-frequency receiver. The received signal power under a target packet error rate is rapidly detected by utilizing an improved algorithm, such that the sensitivity of the receiver is obtained; furthermore, the number of data packets, the measurement packet error rates of which need to be detected at each time, under a certain confidence coefficient condition can be obtained according to a probability calculation method; and thus, the one-time measurement time is greatly reduced. The method and the device disclosed by the invention have the advantages that: calculation of the current method for measuring the sensitivity of the receiver is greatly simplified, such that the detection efficiency of detectors is increased; the detection method is optimized; therefore, the accuracy rate is ensured; the working efficiency in the field of industrial tests is increased; and the production cost is reduced.

Description

technical field [0001] The invention relates to a method and device for fast detection of sensitivity, in particular to a method and device for fast detection of sensitivity of a wireless radio frequency receiver. The invention belongs to wireless radio frequency communication, electronic measurement, automatic control detection or other related fields. Background technique [0002] Receivers are fundamental components in cell phones, laptop computers, and a variety of wireless devices. Wireless devices must go through various performance tests during the R&D and production processes, including receiver sensitivity tests. Receiver sensitivity is often determined by detecting packet error rates. The packet error rate refers to the ratio of the number of erroneous data packets to the total number of transmitted data packets after the signal is received by the receiver, often expressed in the form of a percentage. The determination of receiver sensitivity is very necessary a...
