Abstract :
In 16Mb/s ultra-high speed infrared transmission mode, If we don´t use special processing methods but directly make the common digital signal as the infrared transmission signal transmission, with a very high proportion of high level in the digital signal, the infrared emission tube will always in launching state, leading to higher transmission dissipation, it will also affect the life of infrared emitting tube at the same time, and the bit error rate is not effectively controlled in the direct transmission. In this paper, a method for the processing of a kind of near distance ultra-high speed infrared transmission signal is introduced. To deal with the infrared transmission signal through the method, it can reduce high level bit rate in the bit stream signal and increase the correlation between the bit, and the power consumption and signal transmission error rate is reduced. At the end of the paper, the feasibility of the method is proved by simulation and calculation.
