An optical space time pulse position modulation(OSTPPM)scheme is proposed to satisfy the com-munication requirement of high transmission rate and better reliability.For the OSTPPM scheme,an improved threshold judgment-based orthogonal matching pursuit(IT-OMP)algorithm with low-complexity and near optimal performance is proposed.The average bit error rate of OSTPPM-IT-OMP scheme is investigated over the exponen-tial Weibull channel,and its analytical expression is verified via Monte Carlo simulation.With the same simulation parameters,the signal to noise ratio of(4,4,2)-OSTPPM-IT-OMP is respectively 3.75 dB and 8.5 dB better than that of spatial pulse position modulation(SPPM)scheme and generalized spatial pulse position modulation(GSPPM)scheme at a bit error rate of 1 x 10-3.With the same transmission bits per symbol,the computational complexity of(3,4,2)-OSTPPM-IT-OMP scheme is reduced by 90.47％and 75.4％compared with(16,4,2)-SPPM and(5,4,2)-GSPPM schemes,respectively.
