5G millimeter wave communications
The millimeter wave band is at the forefront of commercial high-capacity consumer wireless communication systems and is a new era of wireless communication. Due to the high cost of millimeter wave devices, they were previously mainly used in the military. However, with the rapid development of high-speed broadband wireless communication, automotive assisted driving, security inspection, medical testing and other application fields, millimeter wave has also been widely studied and applied in the civilian field in recent years.
At present, the golden communication frequency band below 6 GHz has been difficult to obtain a wide continuous spectrum, which seriously restricts the development of the communication industry. In contrast, the millimeter wave band still has a large number of potentially underutilized spectrum resources. A variety of millimeter wave devices, chips, and applications are in full swing. Relative to the microwave band, millimeter waves have their own characteristics. First of all, millimeter wave has a shorter operating wavelength, which can effectively reduce the size of devices and systems; Second, millimeter waves have abundant spectrum resources and can meet the needs of future ultra-high-speed communications.
This solution is based on USRP devices to implement millimeter wave radio communications. The scheme includes two USRP-LW N321 and two MWM39s as well as a standard gain horn antenna with a maximum signal bandwidth of 200MHz
The system structure is as follows:
The scheme uses software and hardware from software-defined radios for baseband signal processing. In the computer, baseband signal processing can be performed using open source GNU Radio, or commercial LabView, Matlab and other software.
At the transmitter end, the software in the computer will transmit the data through the source coding, channel coding, modulation to generate the modulated baseband waveform data, and then through the SFP port to the USRP-LW N321, USRP-LW N321 will change the digital baseband waveform into an analog baseband waveform signal and finally transmit it through the coaxial line MWM39; The MWM39 module converts the analog signal to 39G and transmits it through the antenna.
At the receiving end, the MWM39 receives a 39G mmWave signal via an antenna and downconverts the signal to a sub 6GHz signal, which is transmitted over a coaxial line to the USRP-LW N321, USRP-LW N321 The input analog baseband waveform is collected into a digital baseband waveform, transmitted to the computer through the SFP port, and the computer synchronizes, demodulates, decodes and other processing of the received data baseband waveform.
