Abstract: Future Free Space Optical (FSO) communication systems have the potential to communicate data at very high rates with very high levels of integrity over distances of up to a few kilometers (for terrestrial links). This technology has also been a candidate for high-speed and highly reliable (BER ~10^-9) communication links between satellites in geosynchronous orbits and ground stations. Since the free space optical medium can induce many forms of distortion (atmospheric turbulence effects, optical beam wander, etc.), the use of a channel code to detect and correct errors during the process of information transfer over the channel is essential. A correctly designed channel code can reduce the raw BER from unacceptable values to values that can be tolerated in many applications. Different kinds of error-correcting codes are used for FSO like Hamming Code, Reed-Solomon Codes, Turbo, and LDPC Codes.
Keywords: FSO (free space optics), FPGA (field programmable gate array), BER (Bit error rate), FEC (forward error correction).
