access icon free Block error rate performance of OOK free-space optical links over gamma–gamma turbulence channels with generalised non-zero boresight pointing errors

The authors consider a point-to-point optical wireless communication link with on–off keying (OOK) modulation scheme. The propagation is deteriorated by the joint effects of gamma–gamma atmospheric turbulence and misalignment induced fading described by a non-zero boresight pointing error model. Mathematical expressions are derived for the average block error rate and their accuracy is verified through numerical simulations with Monte Carlo method.
