Abstract : Optical wireless communication can provide high speed, secure and cost effective broadband connection to the common end-users. The channel for optical wireless or free space optical communication (FSOC) can be well modeled using the Málaga distributed turbulence ($\mathcalM$-distribution) channel which is a newly proposed generalized channel model. In this paper, the performance of a single input single output FSOC link over $\mathcalM$-distribution turbulence fading channel in the presence of misalignment fading (pointing error) is studied. At the transmitter, the Differential phase shift keying (DPSK) subcarrier intensity modulation (SIM) is used for sending the symbols. The closed form expressions for the bit error rate, ergodic channel capacity and the outage probability together with their asymptotic performance at high received signal-to-noise ratio are derived to study the overall system performance against the channel fading.
