Comparison of BER and Bandwidth of OOK, PPM, PAM and BPSK for FSO Communication
Keywords:
Free Space Optic, Bit Error Rate, modulation techniqueAbstract
In this paper most efficient modulation technique having minimum bandwidth and best Bit Error Rate (BER) for Free Space Optics (FSO) communication system has been investigated. One of the reasons for BER in FSO is atmospheric turbulence. A model of weak atmospheric turbulence is discussed. The mathematical model of BER and bandwidth efficiency are analyzed and compared.
