discrete wavelet transform for image watermarking

用MATLAB，对OFDM系统进行仿真，其中的信号为BPSK信号。(using MATLAB, the OFDM system simulation, the signal for BPSK signals.)

Matlab programs: A pendulum is a weight suspended from a pivot so that it can swing freely. SNR-Signal-to-noise ratio (often abbreviated SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise.
