Ultraviolet scattering communication has the capability of none-line-of-sight transmission, but it is limited by low receiving power and data communication rate. In this paper, digital pulse interval modulation (DPIM) and dual head pulse interval modulation (DHPIM), which have variable intensity modulation order and no requirement for symbol synchronization, along with on-off keying (OOK) modulation and pulseposition modulation (PPM) are analyzed with packet error rates for ultraviolet scattering communications. To match with the photon counting detection system, a detection model of Poisson counting plus Gaussian photon multiplication and thermal noise is adopted. Using this model, an accurate threshold equation is derived. This adaptive threshold minimizes the packet error rate according to power, rates and other parameters in system structure. Simulated packet error rates of OOK, PPM, DPIM and DHPIM are compared in different scattering channels in this paper.

Performance of on-off keying (OOK), digital pulse interval modulation (DPIM), and pulse position modulation (PPM) schemes are researched for ground-to-satellite laser uplink communications. Packet error rates of these modulation systems are compared, with consideration of the combined effect of intensity fluctuation and beam wander. Based on the numerical results, performances of different modulation systems are discussed. Optimum divergence angle and transmitted beam radius of different modulation systems are indicated and the relations of the transmitted laser power to them are analyzed. This work can be helpful for modulation scheme selection and system design in ground-to-satellite laser uplink communications.

Diversified wavefront deformation is an inevitable phenomenon in intersatellite optical communication systems, which will decrease system performance. In this paper, we investigate the description of wavefront deformation and its influence on the packet error rate (PER) of digital pulse interval modulation (DPIM). With the wavelet method, the diversified wavefront deformation can be described by wavelet parameters: coefficient, dilation, and shift factors, where the coefficient factor represents the depth, dilation factor represents the area, and shift factor is for location. Based on this, the relationship between PER and wavelet parameters is analyzed from a theoretical viewpoint. Numerical results illustrate the validity of theoretical analysis: PER increases with the depth and area and decreases if location gets farther from the center of the optical antenna. In addition to describing diversified deformation, the advantage of the wavelet method over Zernike polynomials in computational complexity is shown via numerical example. This work provides a feasible method for the description along with influence analysis of diversified wavefront deformation from a practical viewpoint and will be helpful for designing optical systems.
