Abstract

The invention discloses a forced integer precoding method of a visible light communication system. Firstly, a mean square error minimization model is established, then the mean square error minimization model is converted into iterative solution of a non-convex problem, in one iteration, the mean square error minimization model is split to obtain a model for optimizing a transmitting precoding matrix and a model for optimizing a forced integer matrix respectively, the transmitting precoding matrix is solved by using a convex approximation iteration method, a compulsory integer matrix is solvedby using a greedy method, and iteration is stopped when a convergence condition is met, so that the solved precoding matrix and the compulsory integer matrix are final results, otherwise, the next iteration is continued. According to the invention, a smaller mean square error is obtained under the same optical power constraint condition.

Description

technical field [0001] The invention relates to a forced integer precoding method of a visible light communication system, belonging to the technical field of visible light communication. Background technique [0002] At present, in the application of forced precoding in visible light communication systems, there are forced precoding designs for single-user multiple-input multiple-output systems, and forced precoding designs with signal-to-interference-noise ratio as the research direction. The research and application of multi-input single-output system and mean square error as the optimization goal are less. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a forced integer precoding method for a visible light communication system. Firstly, the mean square error minimization model is established, and then the mean square error minimization model is transformed into a non-con...
