Embodiment Construction

[0050] The present invention will be further described below in conjunction with specific examples.

[0051] In this paper, a three-dimensional Cartesian coordinate system is used to construct the transceiver system. In addition, we assume that the system is located in a clear ocean water quality environment. Without loss of generality, we assume that the initial emission plane of the photon is the X-Y plane, the light beam is transmitted along the positive direction of the Z axis, the initial weight of a single photon is 1, and the weight threshold of a photon is 10 -4 .

Abstract

The invention discloses a UWOC system channel characteristic MCNS method based on a space coordinate transformation technology. The UWOC system channel characteristic Monte Carlo simulation method is based on the coordinate transformation technology, with a receiver plane having a certain inclination angle relative to an incident optical axis, and having an FOV. According to the method, by means of the thought of coordinate rotation in plane analytic geometry, an equivalent symmetric receiving and transmitting system of photons is constructed, namely, photons are emitted in an original asymmetric coordinate system, judgment of the photons is converted into a new symmetric coordinate system through a coordinate rotation method, and the method can ingeniously solve the problem that accurate judgment cannot be achieved. The invention provides a rapid and accurate calculation method for Monte Carlo channel characteristics of the UWOC system, and overcomes the defects of a traditional simulation algorithm.

Description

technical field [0001] The invention relates to a UOWC system channel characteristic MCNS method based on space coordinate transformation technology, and belongs to the technical field of wireless optical communication. Background technique [0002] In recent years, with the rapid development of wireless communication technology and the deepening exploration of marine resources in various countries, people's demand for underwater high-speed and reliable wireless communication is becoming more and more urgent. Under this background, Underwater Wireless Optical Communication (UWOC) has attracted many scientific researchers because of its high transmission rate, large bandwidth, and low delay, which are far superior to traditional underwater acoustic and short-distance radio frequency communications. It has gradually become a new research hotspot and technology exploration frontier in the field of wireless communication. Among the many technical problems to be solved in the UO...
