<p>A method for encoding a data symbol vector in an OFDM symbol and decoding an OFDM symbol to recover a data symbol vector encoded therein, the method comprising: receiving a vector of values; generating at least one input spatial light pattern responsive to the vector; generating for each input spatial light pattern an output spatial light pattern that is an interference pattern produced by light from the input spatial light pattern; sensing the output spatial light pattern at discrete spatial points and generating signals responsive to the sensed light; and if the vector represents a data symbol vector, using the signals to encode the data symbol vector in an OFDM signal and if the vector represents an OFDM symbol, using the signals to recover a data symbol vector encoded in the OFDM symbol.</p> |
