With the innovation of computer hardware technology and software technology, virtual simulation technology has been applied in various fields, including sports training and basketball teaching process. In this paper, the basketball technology actions optimization system is designed by using MATLAB virtual simulation method, and the initial signal calculus model of basketball technology actions is established by using wireless sensor signal transmission principle, and then using the trained neural network method carries on processing for the initial signal, combining the approximation degree of optimal training signal and original signal determine the validity and reliability of the simulation. Through the simulation, we finally get the optimization allocation effect of the number of neurons’ best basketball technology actions, which provides a new computer method for the exploration of basketball training new method.
