The invention discloses a reconfigurable direct radio frequency modulation transmitter architecture applied to multiple modulation modes, which comprises an L modulation link and an H modulation link, and each link is subjected to phase modulation and amplitude modulation by an I path and a Q path respectively. Through the arrangement of a reconfigurable switch, when only an L link participates in work, QPSK, STAR-QAM, 8PSK and 16-QAM modulation schemes are generated; and when the L link and the H link both participate in work, a 16-QAM (Quadrature Amplitude Modulation), 64-QAM and 256-QAM higher-order modulation scheme is generated. A reconfigurable three-path Doherty power amplifier output inverter network structure is provided, and when a modulation link generates a low-order modulation scheme, the output is a two-path series Doherty power amplifier structure; and when the modulation link generates a high-order modulation scheme, the output is a three-path series-parallel Doherty power amplifier structure. The overall efficiency of the transmitter is improved while the loss and the power consumption are reduced.

This invention discloses a multi-level fusion communication scheduling method and system, relating to the field of industrial processing communication scheduling technology. It solves the technical problem in existing technologies where, for a single process, the communication needs of each stage cannot be met while avoiding resource idleness. Specifically, it employs a hierarchical progression from "overall process scheduling → specific scenario scheduling → risk and hazard scheduling," covering the communication needs of different dimensions of the industrial processing production line and forming a complete multi-level fusion scheduling system. All scheduling is based on "actual scenario parameters," avoiding the rigidity of static scheduling and achieving dynamic and precise allocation of communication resources, balancing transmission efficiency and stability. By optimizing communication scheduling, from three levels—"reducing unnecessary scheduling," "allocating resources on demand," and "avoiding risks and hazards"—it ultimately ensures the qualified operation, efficient control, and low-risk operation of the industrial production line, providing communication-level support for the overall efficiency of the production line.

This invention provides a low-power, ultra-long standby FPV drone image transmission system and its implementation method, comprising: an RF transceiver, a 1-to-2 RF switch, an RF front-end module, and a 1-to-4 RF switch; the signal output terminal of the RF transceiver is electrically connected to the signal input terminal of the 1-to-2 RF switch; the two signal output channels of the 1-to-2 RF switch are respectively electrically connected to the RF input pin of the RF front-end module and the signal input terminal of the 1-to-4 RF switch; the signal output terminal of the RF front-end module is electrically connected to another signal input terminal of the 1-to-4 RF switch; the output terminal of the 1-to-4 RF switch is connected to an antenna. In scenarios where takeoff is not in progress, this invention can shut down the RF amplifier (PA) in the RF front-end module, significantly reducing power consumption and fundamentally solving the heat dissipation problem. Therefore, the image transmission system can operate normally for extended periods without crashing, greatly improving the user experience.

This invention relates to the field of wireless communication technology and proposes a base station site selection method for a 5G AeroMACS system, considering the base station site selection problem from three aspects: base station deployment planning, spectrum planning, and network optimization. In the planning phase, the optimal location of the 5G base station can be scientifically determined, parameters such as inter-site spacing, antenna height, and antenna type can be optimized, and coverage effects can be evaluated. This invention abandons the traditional practice of base station construction based solely on experience, ensuring that the base station can effectively allocate spectrum and control interference. In the high-traffic and complex environment of airports, it can efficiently utilize wireless resources, improving network operating efficiency and user experience.
