| description | Signals transporting orbital angular momentum (OAM) have
gained significant interest due to their unique structure and capability for
increasing the channel capacity. OAM beams are orthogonal and can be
multiplexed to increase link capacity in different scenarios. The collective
combination of radio OAM modes and OFDM modulations in outdoor conditions has
not been extensively explored. This paper depicts an analysis of multiple OAM
modes transmitted as narrowband subcarriers using orthogonal frequency division
multiplexing (OFDM) modulation with
outdoor free space optical channel measurements based on OAM modes. OAM-OFDM
simulations were conducted to investigate the performance of QPSK, 16QAM, and
64QAM baseband modulation and demodulation mechanisms, with code rates ½ and ¾
respectively. Four outdoor OAM free
space optical channel characteristics parameters were applied. The throughput,
bit error rate (BER), and packet error rate (PER) were evaluated. The results
show that OAM +4 Mode outperforms other OAM modes in terms of BER and PER. In terms of the throughput, 64 QAM at code
rate ¾ outperforms other coding schemes and code rates, for all OAM modes. |
