First, applying FM technology to UV gas discharge lamp, the electric signals will be converted into optical signals. Next, optical signal is received by photomultiplier hot women's dresses tube in receiver, which is converted into electrical signals. Then, shop 4u blog for shirts electrical signal is filtered, amplified and converted into TTL pulse signal. Finally, the original signal can be extracted by FPGA based on the principle of zero-crossing detection from the chi hair straightener modulated signal. Besides, it is difficult to improve the data rate of UV communication system. The cheap polo shirts maximum data rate is only 9600bit/s, which can not directly meet speech ralph lauren polo shirts transmission. Consequently, the real-time speech compression technology has become the key point of the system. In order to meet the real-time voice transmission demand of UV Lacoste Polo Shirts communication system, the speech encoding and decoding chip AMBE-1000 is selected.Base on the above research, the prototype of ultraviolet communication has been designed and realized. Experimental results indicate that this device is flexible and stable, Within the distance of 200m, the real-time speech communication and character transmission can be performed in the the transmission rate of 9600bit/s. In ordor to improve transmission distance and full-duplex communication, some good suggestions will be proposed in the end of this paper.
