Abstract
Radio Over Free space optics is a promising and under developed technique in a optical communication system to increase capacity and decreasing the system costs for future broadband communication. In this work, analyzed the performance of radio over free space optical communication system in the effect of various atmospheric conditions. A signal of 10Gbps is transmitted through Radio Over Free Space Optical Link and proposed system has to be evaluated in terms of Q-Factor, BER and Eye Opening Factor. The various advanced modulation formats NRZ, CSRZ, DPSK have been investigated in Radio over free space optical link. Among them, it is ensured that DPSK is the most accurate, well suited and simplest technique for RO-FSO channel. It has been observed that DPSK performs better at long range than CSRZ, NRZ techniques. Superior performance shows that DPSK which has simple design and less cost, perform best at a higher transmission range at the data rate of 10Gbps. All the results are observed using NRZ, RZ, CSRZ, DPSK modulation Formats and amplifier is not incorporated in this work.

Keywords- RO-FSO (Radio over Free space optics), RF (Radio Frequency), DPSK (Differential Phase Shift Keying), Q-Factor.
