In order to effectively use directional antenna spacedivisionmultiplexing features, while reducing some of its directional influence to bring the need to propose a new wireless MAC protocol.
A timing and frequency synchronization scheme based on FH sequence is proposed for the free space optical communication Orthogonal frequency DivisionMultiplexing (FSO-OFDM).
