时域同步平均法，在降噪上有很明显的帮助TSA(Time-domain synchronous averaging method, the noise has obviously help)

将OFDM技术运用在可见光通信的研究，并且把OFDM的高峰均比这一缺点进行了建设性的运用。(In particular, the use of OFDM (orthogonal frequency division multiplexing) for intensity modulation is investigated. The high peak-to-average ratio (PAR) in OFDM is usually considered a disadvantage in radio frequency transmission systems due to non-linearities of the power amplifier. It is demonstrated theoretically and by means of an experimental system that the high PAR in OFDM can be exploited constructively in visible light communication to intensity modulate LEDs. It is shown that the theoretical and the experimental results match very closely, and that it is possible to cover a distance of up to one meter using a single LED.)

The function to obtain indexes of inner of window points in the windoving procedure for each point in 2D surface. It allows to avoid cyclic operation which too slowly.

手写数字识别程序，matlab运行前，先点击安装控件，内部有三种模型，GUI形式，使用方便(Handwritten numeral recognition program, matlab run before, first click on the installation of control, there are three kinds of models, GUI form, the use of convenience)
