Description
Technical Field
The present application relates to the field of wireless communication testing technologies, and in particular, to a system and a method for testing signaling of wireless ad hoc network devices based on software defined radio.
Background
Testing of wireless communication devices is generally divided into signaling testing and non-signaling testing. The non-signaling test is mainly used for measuring whether each hardware index and physical layer index of the wireless equipment meet the specification requirements, and the signaling test is mainly used for measuring whether the interaction process between the wireless communication equipment meets the specification requirements of a communication protocol. The non-signaling test is a test based on a non-signaling pattern of the device. The main testing method is to set the equipment to be in a transmitting-only state or a receiving-only state for testing, and at the moment, the instrument only transmits data or only analyzes the received data. The test method for calibrating the sensitivity index by throughput rate backoff is, for example: the non-signaling sensitivity test can only reflect the unpacking capability of a receiver, but cannot be directly used as a method for measuring the receiving capability of the wireless devices because the signaling interaction retransmission exists between the wireless devices in fact, and if the test instrument does not have the signaling capability, the sensitivity parameter calibrated by the throughput rate rollback under the signaling cannot be measured.
The main testing method of the signaling test is to use a testing instrument (such as a CMU200) to simulate an auxiliary testing device, send signaling with a device to be tested through the testing instrument, demodulate data information sent by the testing instrument by the device to be tested, compare the obtained information with information actually sent by the testing instrument, and judge the receiving performance of the device to be tested; similarly, the test instrument demodulates the data information sent by the device to be tested, and detects the obtained waveform to obtain the sending performance of the device to be tested.
Wireless ad hoc network devices are an important type of device in the field of wireless communications. Due to the fact that the wireless ad hoc network equipment is complex in market conditions, numerous in design companies and free of complete industry universal standards, communication protocols of the wireless ad hoc network equipment designed by the design companies are different, and therefore no special signaling test instrument in the field of wireless ad hoc networks exists in the market. At present, a point-to-point test method between devices is generally adopted for wireless ad hoc network devices, and the test efficiency is low.

It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, there is provided a wireless ad hoc network device signaling test system based on software radio, comprising: software radio equipment, signaling test FPGA equipment and test signal transceiving equipment.
The software radio equipment is used for generating corresponding signaling test FPGA configuration data by using a software radio technology according to preset signaling test requirement data and communication protocol parameters of the wireless ad hoc network equipment to be tested, and is used for obtaining a signaling test result of the wireless ad hoc network equipment to be tested according to the transmitting performance parameters and the receiving performance parameters sent by the signaling test FPGA equipment.

The test signal transceiver is used for generating a corresponding signaling test analog signal according to the signaling test digital signal, sending the signaling test analog signal to the wireless ad hoc network device to be tested under the control of the signaling test FPGA device, receiving a signaling test feedback analog signal sent by the wireless ad hoc network device to be tested in response to the signaling test analog signal under the control of the signaling test FPGA device, generating a corresponding signaling test feedback digital signal according to the signaling test feedback analog signal, and sending the signaling test digital signal to the signaling test FPGA device.
Specifically, the hardware of the software defined radio may be, but is not limited to, various servers, personal computers, laptops, with the software defined wireless platform installed. When the system is used, firstly, according to communication protocol parameters of the wireless ad hoc network equipment to be tested and testing requirements of the wireless ad hoc network equipment, corresponding testing signal parameters are set in the software radio equipment so as to generate a testing waveform conforming to a communication protocol adopted by the equipment to be tested. Such as a data encoding method, a data encryption method, a signal modulation method, a channel allocation method, etc. for obtaining a communication protocol of the wireless ad hoc network device. And according to the obtained communication protocol parameters, programming FPGA program configuration data required for generating the corresponding test waveform by using a software radio platform. And then, configuring the signaling test FPGA equipment by using the generated FPGA program configuration data so that the signaling test FPGA equipment can generate a corresponding test waveform, namely a signaling test digital signal. It should be noted that, the signaling test FPGA device not only needs to generate a test waveform, but also needs to process a test feedback waveform returned by the device to be tested to obtain a signal parameter required by a test result, so that when the flexible wire radio platform compiles FPGA program configuration data, the signaling test FPGA needs to have a corresponding processing capability on the test feedback waveform returned by the wireless ad hoc network device to be tested, that is, data can be obtained from a specified channel, and a series of operations such as demodulation, decryption, decoding and the like are performed to obtain a data content of the test feedback waveform; and analyzing and processing the power parameter of the feedback waveform to obtain the emission performance parameter of the equipment to be tested.
And then, the test signal transceiving equipment processes the signaling test digital signal to obtain a corresponding analog signal, and sends the analog signal to the equipment to be tested. The equipment to be tested demodulates the received analog signals to obtain the data sent in the test data. Receiving the influence of the receiving performance of the device to be tested, the demodulated data and the data sent by the software radio device may have a deviation, and the degree of the deviation may be represented by Bit Error Ratio (BER), so the BER between the demodulated data and the originally sent data may indicate the receiving performance of the device to be tested. And then, the equipment to be tested returns a data packet according to the received signaling test analog signal, namely, the signaling test feedback analog signal is sent. The signal is received by the test signal transceiver, converted into a corresponding digital signal and then sent to the signaling test FPGA device. And processing the received signaling test feedback digital signal by the signaling test FPGA according to the configured communication protocol, carrying out waveform analysis according to the test requirement to obtain the required waveform parameter, and sending the obtained waveform parameter to the software radio equipment. And the software radio equipment analyzes and counts the waveform parameters to obtain the signal transmission parameters of the equipment to be tested.

A test feedback signal of the device to be tested enters a receiving link through a circulator, the gain control is carried out on the test feedback signal by an adjustable attenuator at a receiving end under the control of the FPGA, the test feedback signal enters an analog-to-digital conversion module through a low-noise amplifier and is converted into a digital signal, and the digital signal is transmitted to the FPGA for processing. And the FPGA extracts data required for generating a test result from the received digital signal according to the pre-configured program data and transmits the data to the SDRLab.

And the equipment to be tested generates and returns a data packet according to the received data and sends the data packet through a test feedback signal.
