Enhance the performance of free space optical (FSO) communication due to atmospheric turbulence via the dual diffuser modulation (DDM)
Abdul Rahman, Kram; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Anuar, Mat Safar, Ir. Dr.; Hilal Adnan, Fadhil, Dr. (Trans Tech Publications, 2013-12)This paper focus on mitigating the atmospheric turbulence effect in free space optical communication using dual diffuser modulation (DDM) technique. Phase screen diffuser located on transmitter create 'new' beam wave to ... -
Performance of optical OFDM systems using new PAPR reduction approach
Hilal Adnan, Fadhil; Hasoon, Feras N.; Syed Alwee Aljunid, Syed Junid; Ahmad, H. Y.; Hamza Mohammed Ridha, Al-Khafaji (EBSCO Publishing., 2012-03)The major drawback of optical orthogonal frequency division multiple access (OFDM) system is their inherent intensity noise and peak average power ratio (PAPR). We introduce a new direct detection receiver based on PAPR ...
