Image communication system based on chaotic FH-OFDM technique

A novel chaotic FH-OFDM communication system based on OFDM (Orthogonal Frequency Division Multiplexing) and FH (Frequency Hopping) is presented. The carriers frequency of OFDM are controlled by chaotic pseudo random sequences. In every iteration period, the method adopts the different keys. It analyzes the balance, the distance and the maximum Hamming correlation of this FH sequences in theory and numberic simulation. The application of and different demodulation technology in video image communication system is put emphasis on the research. Simulation result shows that the theory analysis is accordance with the experiment result. The system has the advantages in low Signal-to-Noise condition and video transmission performance in AWGN channel.
