In orthogonal frequency division multiplexing (OFDM) communication systems, due to the environmental impact generated the multipath effect caucused signals distortion and attenuation in transmitted process, and due to relative motion between transmitter and receiver caused the Doppler Effect that makes the signal carrier offset. Therefore, the knowledge of the channel characteristics is very important...
This paper presents two main concepts. The first one is a new concept of artificial neuron, different from the classic approach. The second one is a proposal of a system that simulates the human visual perception in artificial intelligence systems based on what is known at this date on the human visual system at neurological and cellular levels.
