Abstract

A temporal-spatial continuous Gaussian communication channel model is built by information theory. And the channel capacity is analyzed. Then a send-receive system scheme for imaging communication is proposed and the basic constrain conditions for system design are derived. The system performance is also analyzed and evaluated with spatial bandwidth product. After that an experiment is carried out for transmission 13X15 2-D pattern image through 30m distance. The expected performance is examined by the experiment results. At last a signal detection technique for imaging communication and corresponding pattern code and decode scheme are proposed.
