Abstract

The invention discloses a method to enhance WCDMA weak signal detection based on the energy screening device for the SDR platform, which relates to the detection and signal recognition technology of the weak radio signal in the field of radio communication. The method, through adding the energy screening device to the SDR software-based radio platform, collects and screens the results calculated by the uplink pilot energy signal calculator, thus effectively improving the detection distance from the whole SDR software radio platform to the target WCDMA mobile transmission signal and the detection accuracy. The energy screening device can work out whether the received WCDMA mobile phone signal is the signal transmitted by the target according to the calculation results of the uplink pilot energy signal calculator, thereby improving the accuracy of the target detection. Resolution of the critical distance is greatly enhanced through the statistical analysis of data probability on the results of the uplink pilot energy signal calculator, thus the capture distance is greatly enhanced.

Description

technical field [0001] The present invention relates to the detection and tracking technology of weak WCDMA signals in the field of radio communication, and in particular to a method for detecting weak WCDMA signals based on an SDR platform using an energy brush selector, which has a wide range of energy capture for detecting target WCDMA signal sources, and can detect The advantages of high accuracy. Background technique [0002] With the wide spread of WCDMA networks around the world, more and more users use WCDMA mobile phones for mobile communication. Private network wireless communication and its rescue and disaster relief require accurate detection of the WCDMA signal source of the target user, so as to save a large number of people in disasters. trapped people. Since the domestic WCDMA network uses a large number of 2.1G frequency bands, the signal attenuation speed is faster than other network standards, thus affecting the detection range of the WCDMA target signal ...
