“…Digital pulse interval modulation (DPIM) has a variable symbol length; thus, it has a higher spectral efficiency and transmission capacity than other modulation methods. However, continuous errors are likely to arise in DPIM demodulation processing because the demodulation error of one symbol leads to a series of symbol demodulation errors [21][22][23]. OOK and PPM are referred to as synchronous modulation because the data are mapped in fixed-length symbols, and the signal is subjected to strict symbol synchronization processing during demodulation.…”

In free-space optical (FSO) communication, with the increase of bit resolution of M, the required bandwidth of PPM and DPIM increase sharply, and the bandwidth efficiency are extremely low. There is also a clock synchronization problem in the demodulation process of PPM and OOK. We propose a pulsed-laser pulse-number modulation (PNM) method to address the high required bandwidth and low bandwidth efficiency for high-order modulation in FSO communication with traditional modulation methods. The symbol structure, power efficiency and bandwidth properties of PNM are presented. The modulation and demodulation of PNM are simple and easy to implement without complex clock synchronization processing. Additionally, we use the FPGA as the core controller to build an FSO communication system, which realizes accurate modulation and demodulation of data with PNM modulation method under the communication distance of 27 m and the bit rate of 2.5K bps.

“…IsOWC offers high bit rate, high quality and more security [6]. Although the Optical communication that works in vacuum is considered to be lose less but the transmitted signal suffers different path losses that increases with the communication distance [7]. Integration of Dense Wavelength Division Multiplexing (DWDM) with IsOWC provides high capacity and pacy network.…”

Inter-satellite communication based on lasers (LIC) is a possible choice for future satellite networks because to ultra-high capacity and speed systems that may be achieved using compact, light-weight, and low-power optical equipment. The performance of a 64 × 40 GB/s optical wireless system with polarisation diversity for dense WDM is investigated in this research paper. Using a DWDM system with a channel spacing of 50 GHz, a high-speed system is achieved to meet the broad bandwidth needs of data services in satellites. A polarisation diversity approach is implemented in the system to decrease polarisation crosstalk and nonlinearities among nearby WDM channels. Furthermore, a comparison of the polarisation interleaved and traditional DWDM-OWC systems is performed. In addition, it was discovered that a system with varying states of polarisation across neighbouring channels performs better in terms of Q-factor and BER than a traditional system.

The performances of fiber-based free-space optical (FSO) communications over gamma-gamma distributed turbulence are studied for multiple aperture receiver systems. The equal gain combining (EGC) technique is considered as a practical scheme to mitigate the atmospheric turbulence. Bit error rate (BER) performances for binary-phase-shift-keying-modulated coherent detection fiber-based free-space optical communications are derived and analyzed for EGC diversity receptions through an approximation method. To show the net diversity gain of a multiple aperture receiver system, BER performances of EGC are compared with a single monolithic aperture receiver system with the same total aperture area (same average total incident optical power on the aperture surface) for fiber-based free-space optical communications. The analytical results are verified by Monte Carlo simulations. System performances are also compared for EGC diversity coherent FSO communications with or without considering fiber-coupling efficiencies.
