Abstract
Free space optics is one of the emerging technology of optical wireless communication which refers to propagation of light beams through atmosphere for broadband communication. It is a promising alternative solution for RF network, as it provides stable data transmission and highest data rates. However performance of this system could be prominently degraded due to various atmospheric conditions that may lead to increase in bit error rate and affect link sustainability. This paper presents analysis of proposed FSO system with comparative study of different modulation techniques under weak turbulence at 1550 nm wavelength in terms of BER and Q factor so as to mitigate adverse effects and improve efficiency.
