| Summary: | In this paper, an alternative implementation of the hybrid free space optical/radio frequency based on a millimeter wavelength wireless communication system without requiring channel state information is presented. The proposed hybrid system transmits the same data with the same data rate over both links simultaneously. The well-known diversity selection combining scheme is considered for combining the received signals in the electrical domain. A new closed-form expression for the average bit error rate and outage probability are derived in order to trace the system's performance over various turbulence channel conditions. The analysis of the results of the proposed system’s performance clearly indicates that the proposed system is advantageous as it exploits the complementary properties of FSO and RF channels, even in strong turbulence channel conditions. In addition, the performance comparison demonstrates the proposed system’s superior performance compared with the FSO-only system. |
