In this paper we propose a watermarking system that uses the biorthogonal discrete wavelet transform, DWT and the message is encoded before embedding. The proposed watermarking method is very simple, implying four steps: turbo coding of

在AWGN信道下，采用turbo编码和BPSK调制的收发仿真-The simulation contains the transimission and reciever, which is in AWGN channel with turbo coded and the modulation is BPSK.
