“…In [21], optical double sideband (ODSB) and optical tandem sideband (OTDB) modulation in OFDM were compared, and the findings demonstrated that OSSB modulation performs well at high rates in Is-OWC systems. Author in [22] studied Is-OWC system with homodyne detection and double sideband suppressed carrier (DSB-SC) modulation and with improved receiver. In [23], Suppression of sidebands using Brillouin scattering in radio over fiber systems was demonstrated.…”

Insophisticated situations coming from developing multimedia applications and the exponential increase in the number of smart sensors and devices, future wireless networks will ensure high reliability, low latency, scalability, as well as better quality-of-service.Optical wireless communication (OWC) becomes more important because it can take advantage of the light medium's unique selling points over RF, such as immunity to electromagnetic interference (EMI), ultra-high capacity, the ability to communicate wirelessly through water, and the ability to provide additional security. Dual polarization (DP) enabled multilevel modulations in inter satellite optical wireless communication (Is-OWC) are potential and capacity building techniques to cope up with bandwidth explosive demands. Therefore, inthis work, a reach enhanced single channel Is-OWC is proposed using Double Sideband Suppressed (DSS) dual polarized (DP) Quadrature phase shift keying (QPSK) modulation. Spectral efficiency of carrier is improved through DSS technique using Mach-Zehndar modulator (MZM) and millimeter wave (mm-wave). Further, pulse width reduction, nonlinear effects suppression, carrier phase estimation (CPE) and frequency offset estimation (FPE) is performed by Digital signal processor (DSP) in coherent receiver of PDM-QPSK. Performance comparison of DP-QPSK and DSS-DP-QPSK is performed at different link lengths in terms of log BER and error vector magnitude (EVM%). Results revealed that proposed system i.e., DSS-DP-QPSK at 160 Gbps data rate covers 44,000 km Is-OWC distance with acceptable log BER as compared to 40,000 km in DP-QPSK due to improved spectral efficiency of carrier spectrum of proposed system.

Inter-satellite optical free space communication enabling radio frequencies (RF) is prevalent nowadays due to high speed, prolonged reach, and improved security. Inter-channel interference is the predominant performance deteriorating limitation in wavelength division multiplexed (WDM) based optical communication-based satellite systems (OCSS). Therefore, in this work, a hybrid 16 × 40 Gbps OCSS system with 10 GHz RF signals is presented employing transmitter diversity. Further, three different arrangements of NRZ, AMI, and NRZ-AMI are investigated in terms of log bit error rate (BER) and signal-to-noise ratio (SNR) over a 30,000 km link distance. Results revealed that the transmitter diversity-based NRZ-AMI arrangement offered the best performance followed by AMI non-transmitter diversity system. The proposed system is flexible, economical, and easy to realize.
