Research on Millimeter Wave Communication System Based on Integrated Computer Artificial Intelligence Technology

The ADF4002 and two ADF5355 frequency modulation synthesizers are integrated to realize a millimeter wave communication system which is suitable for both medium and high frequency. The output power of MMW communication system is regulated by digital control of attenuator and amplifier circuit. The ADF5355’s PLL and frequency doubling circuit provides the RF module with an 8.4-11.2GHz bandwidth and 100 MHz step frequency tunable local oscillator signal. The channel modeling of the system with lateral axis migration is carried out based on the OAM mode migration characteristics. The system includes the theoretical derivation of the modal power distribution under the offset and the construction of the channel transmission matrix. Finally, the hardware structure of the system is analyzed and tested in detail, so that it has the advantages of low noise and low clutter. It is found that the lower the modal value of the selected mode set or the larger the step distance, the smaller the influence of the deviation on the system performance. The local oscillator components and transceivers are independent, which can effectively reduce problems such as source noise leakage and RF interference, reduce the PCB size of the transceiver, and make each component more flexible.
