Paper Abstract

Affected by atmospheric turbulence and multipath transmission, inter-symbol interference (ISI) is generated, and communication speed is limited in the channel of non-line-of-sight ultraviolet (NLOS UV) communication. Thus, MIMO space division multiplexing (MIMO-SDM) technology has a significant effect to reduce co-channel interference, fading and improve the transmission rate. Combined with characteristics of UV channel and noise, model of UV communication MIMO channel and channel capacity is developed, and the application of SDM technology based on vertical bell laboratories layered space-time coding (V-BLAST) is investigated. Also bit error rate (BER) performances with zero-forcing (ZF), minimum mean square error (MMSE) detection algorithm are obtained. Simulation results show that the capacity of UV communication MIMO channel is related to the number of transmit and received antennas , and channel SNR. And the BER performance with MMSE detection algorithm is better than ZF detection algorithm.
