Research on the Application of Diversity Reception Technology of Weak Turbulence Channel UV Light Communication
摘要
Abstract
Aiming at the problem that the weak turbulence channel degrades the quality of UV light NLOS communication,the bit error rate formula using OOK modulation flicker attenuation is derived for the log normal model.The simulation results show that in the weak turbulence channel,flicker attenuation leads to the deviation of the light intensity probability density distribution curve from the light intensity mean value,resulting in the deterioration of the signal-to-noise ratio.The stronger the turbulence intensity is,the higher the bit error rate of the communication system is.Under the same conditions,the maximum ratio combining(MRC)has the best performance,the equal gain combining(EGC)takes the second place,and the selective combining(SC)is the worst.With the increase of the number of antennas,the performance of the UV light communication system can be improved.关键词
