In this embodiment, a WiFi signal is sent by an AP, reaches a receiving end via a wireless channel, and CSI is obtained at the receiving end by using CSITool extraction. And extracting an M x N x 30 dimensional CSI matrix for each protocol data packet in the communication process. Where M and N represent the number of receiving antennas and transmitting antennas, respectively, and 30 represents CSI measurement data sampled in the OFDM subcarrier direction (frequency direction) for 30 subcarriers. The method is used for acquiring the first wireless fingerprint information of the user at different positions away from the electronic equipment and the first behavior characteristic information corresponding to each first wireless fingerprint information. For example, first wireless fingerprint information at a position 0.1m, 0.3m, 0.4m and the like from the electronic device and first behavior feature information corresponding to the user may be acquired, where the first behavior feature information includes an unmanned state, behavior feature information when the user is using the electronic device, when the user is away from the electronic device, and when the user is close to the electronic device. The wireless fingerprint information of the user in the unmanned state is used as a reference so as to improve the accuracy of information acquisition.
In one embodiment, the acquiring first wireless fingerprint information of a user at different positions includes:
acquiring CSI amplitude information and CSI phase information according to the received WiFi signals;
and performing compensation processing on the CSI amplitude information and the CSI phase information to obtain the first wireless fingerprint information.
The device used by the application comprises WIFI matching equipment, WiFi sensing equipment and electronic equipment provided with a control system. Certain distance is left between WIFI cooperation equipment and the WiFi sensing equipment, and the WiFi sensing equipment can be arranged in the electronic equipment. The WIFI coordination equipment transmits a WiFi signal, the WiFi signal is transmitted in the space, the WiFi sensing equipment generates a CSI signal from the acquired WIFI signal and stores the CSI signal as a packet file, the packet file is transmitted to the electronic equipment, and the electronic equipment extracts amplitude and phase information of subcarriers in the CSI signal.
In the data acquisition process, in order to obtain enough data packets, the present embodiment may set the response time to 0.02s, that is, 50 data packets are transmitted in one second. A MATLAB may be used to read the envelope file, extracting the amplitude and phase information of the 30 subcarriers of the corresponding CSI. According to the collected CSI data, extracting phase information in each data packet to obtain a measurement phase of the CSI data comprises the following steps: the CSI of each subcarrier is spread, and since the spread phase is approximately linear on 30 subcarriers and the overall slope is negative, the present embodiment performs fitting by using least squares and obtains the fitted result, and the true phase is obtained by subtracting the linear fitting from the phase of all subcarriers after the CSI is spread.
In order to obtain more accurate wireless fingerprint information, after acquiring the CSI amplitude information and the CSI phase information, the present embodiment performs compensation processing on the CSI amplitude information and the CSI phase information to eliminate an amplitude error and a phase error.
Besides being affected by large-scale path loss and shadow fading, the CSI obtained by the receiving end (electronic device) is also affected by other interference factors such as channel noise, multipath effect and system hardware defect, so that the received original CSI data needs to be preprocessed first.
At the receiving end of the Wi-Fi network, firstly, the received continuous analog signal is converted into a discrete digital signal by using an analog-to-digital converter. Then detecting whether the discrete signal contains specific pilot frequency information or not through a packet boundary detector, and if the pilot frequency information is detected, indicating that the current discrete signal is effective data; and then, the receiving end compensates and corrects the effective discrete data signal by using the center frequency offset corrector, and analyzes the effective discrete data signal to obtain CSI data so as to provide reference information for subsequent data decoding. Due to the lack of a clock synchronization mechanism between a sending end and a receiving end in a Wi-F i network and the physical defects of hardware equipment, detection and compensation results of a boundary detector and a central frequency offset corrector have certain deviation, which is particularly shown in that the boundary detector introduces detection time deviation and the central frequency offset corrector causes central frequency compensation deviation. These deviations mainly cause measurement errors in the phase of the raw CSI data. The present embodiment employs a linear transformation method to correct the phase error. The specific compensation method may be implemented by using an existing linear transformation method, and this embodiment is not described again.
After the CSI phase error is compensated, the influence and interference caused by the Wi-Fi signal multipath effect on the CSI amplitude need to be further compensated. In the embodiment, the multipath signal clusters with time delay longer than a certain time are filtered, and amplitude fluctuation between the CSI subcarriers can be smoother through the CSI amplitude values before and after multipath elimination processing, namely, the phenomenon of violent fluctuation of the subcarriers caused by multipath effect is weakened, so that the purpose of weakening or eliminating multipath signal interference is achieved.
In an indoor scene, after data acquisition is finished and CSI information is generated, in order to reduce interference of OFDM on frequency and phase, the present embodiment performs low-pass filtering on CSI to remove noise of high frequency, and the passband cutoff frequency is set to be 30HZ and the stopband cutoff frequency is set to be 80 HZ.
In an embodiment, after performing compensation processing on CSI amplitude information and CSI phase information, obtaining the first wireless fingerprint information includes the following steps:
assuming that the electronic device is provided with 3 antennas, for the CSI data after phase correction, the phases of the 3 antennas on 30 subcarriers are extracted, the invention makes the measured phases of the first antenna and the second antenna on 30 subcarriers different to obtain the phase difference between the first antenna and the second antenna, and according to a similar method, obtains the phase difference between the second antenna and the third antenna, and the phase difference between the first antenna and the third antenna. The phase difference between the 3 antennas of the 30 subcarriers is also a matrix with the dimension of 3 x 30. The 3 x 30 phase difference matrices from each packet are concatenated by row to obtain a row vector of length 90. For each target position, phase difference information among antennas of 100 data packets is extracted, a 100 × 90 phase difference matrix obtained from the 100 data is used as first wireless fingerprint information of the position where a user is located, and the first wireless fingerprint information can well represent a certain geographic position in an indoor scene.
In an embodiment, the determining a wireless fingerprint information boundary condition according to the first wireless fingerprint information and the first behavior feature information comprises:
obtaining the distance between the user and the electronic equipment according to the first wireless fingerprint information;
and determining the boundary condition of the wireless fingerprint information according to the first behavior feature information and the distance.
And after the actual distance between the electronic equipment and the wireless fingerprint information is calculated according to the first wireless fingerprint information, determining the boundary condition of the wireless fingerprint information according to the corresponding first behavior characteristic information. And storing the wireless fingerprint information meeting the boundary conditions of the wireless fingerprint information to construct a wireless fingerprint database.
For example, the distances between the users and the electronic device are calculated to be 2m, 1m, 0.8m, 0.7m, 0.5m and 0.2m respectively according to the first wireless fingerprint information. The corresponding first behavior feature information is respectively: unused, in use, and in use. The fingerprint boundary condition may be set to 0.7 m. That is, with the electronic device as the center, the area with the radius of 0.7m satisfies the fingerprint boundary condition, and the area with the radius of 0.7m does not satisfy the fingerprint boundary condition.
