The invention discloses a transmitting device for inhibiting light intensity flicker by using a sharp light beam. The transmitting device comprises a laser generation module and a phase modulation module. A Gaussian beam is emitted from the laser generation module, is subjected to phase modulation by the phase modulation module and then becomes a frontal beam, the frontal beam is emitted into a space for transmission, and a light intensity flicker suppression effect can be realized at a receiving end. The transmitting device for inhibiting light intensity flicker solves the problem of poor real-time performance of a self-adaptive optical system at the transmitting end, is simple in structure, low in cost and easy to implement, reduces the maintenance difficulty and cost of the system, and can obtain higher receiving power and smaller light intensity flicker results.

The invention belongs to the related technical field of wireless communication, and particularly relates to a method for optimizing user receiving power in a highly directional millimeter wave communication system, which comprises the following steps of: rotating a reconfigurable intelligent surface along a transverse horizontal central axis of the reconfigurable intelligent surface until a downward inclination angle of the reconfigurable intelligent surface is between 0 and a critical value; the high-orientation millimeter wave communication system comprises a reconfigurable intelligent surface, a base station and a single user, and the reconfigurable intelligent surface is located in a far field close to the base station and is vertically placed; the critical value corresponds to a certain expression; specifically, the distance between a base station and the center position of the reconfigurable intelligent surface, the total number of rows arranged in the vertical direction in the reconfigurable intelligent surface, the vertical length of each unit in the reconfigurable intelligent surface, and the incident angle and the reflection angle of the reconfigurable intelligent surface in the vertical placement state before rotation are related to communication system structure parameters.

This invention relates to the field of power line carrier communication technology, specifically to a control method, processor, control device, and storage medium for power lines. The method includes: connecting phases A, B, and C of a power line to the same coupler and setting them to share a common N terminal, forming a three-phase coupling transformer; setting the number of turns of the primary and secondary coils of the three-phase coupling transformer to be equal; and setting the coupling inductance power of the weak current side analog-to-digital converter terminal, the weak current side digital-to-analog converter terminal, and the strong current side phases A, B, and C of the three-phase coupling transformer to be equal. The three parallel communication signals ensure that an interruption in any one channel does not affect the signals of the others, i.e., a phase loss does not cause communication interruption, thus improving the quality of three-phase communication. Phases A, B, and C are synchronized when transmitting and receiving signals, achieving multiple-input multiple-output (MIMO) and enhanced signal strength. The transmit and receive power of the coupler are both increased, improving channel quality and enhancing communication success rate and reliability.
