Abstract :
We experimentally demonstrate m-ary encoding/decoding using visible-light Bessel beams carrying orbital angular momentum (OAM) for free-space obstruction-free optical communications. The bit-error rate (BER) performance of hexadecimal and 32-ary encoding/decoding are investigated. A zero BER of hexadecimal encoding/decoding is observed after decoding 500 symbols with obstruction.
