Abstract	The degradation of the performance in wireless ultraviolet UV communication is due to the presence of the inter symbol interference which is caused by atmospheric scattering of light. The pdf of the received signals is derived, and then we had studied a maximum a posteriori (MAP) equalizer for the UV communication. The results indicate performance of equalizer is nearly not affected by the attenuation coefficient and channel bandwidth for the short range communication, but is sensitive to variation of channel length and bit rate. The bit error rate can vary greatly with the variation of channel length and bit rate and can be reduced significantly when the adaptive power control is used. At last, the optimal lengths of the training sequence and frame are derived.
