“…Advancements in Optical Data Transmission and Security Systems DOI: http://dx.doi.org /10.5772/intechopen.94835 Practical testing and simulations [4] of PPM show that the probability of error is minimum for the maximum likelihood estimate of the stationary beam position, and for the dynamically varying beam position, a filter with a large number of particles provides a close-to-optimal probability of error performance.…”

Optical Communication (OC) for data transmission was introduced more than 30 years ago. It employs two main technologies, fiber optics using a physical wire and Free Space Optical (FSO) wireless transmission. Fiber optics has been well developed over the years in terms of distance, bandwidth, speed, reliability, and other enhancements that contribute to its use. Recent developments in FSO transmission has made it the mainstream and a better alternative compared to RF wireless transmission, concerning all parameters. In this chapter, we focus on advancements in OC that represent innovative ideas of how to enable new methods of secured optical data transmission in different ways and not simply as an extension to current methods and technologies.

Free-space optical (FSO) communications is an important technology that will be used for supporting high data-rates in the backhaul of next generation of wireless communication networks. In this paper, we have compared the probability of error performance of two types of receivers used in FSO today: a receiver based on a single detector, and a receiver based on an array of detectors. The performance of these two receivers is compared for a number of fusion algorithms for an array of detectors such as equal gain combiner (EGC), selection combiner (SC), switched combiner (SWC) and the maximal ratio combiner (MRC). From this study, we conclude that even though the array of detectors adds more noise in the sufficient statistic by virtue of large number of detectors, using more computationally expensive fusion algorithms (such as SC and MRC) can help us achieve a superior probability of error performance as opposed to a single-detector receiver for practical channel conditions. <br>

“…The authors in [2], [6] have proposed beam position estimation and tracking algorithms for a detector array photon-counting receiver concerning a joint beam position tracking and symbol detection scheme for PPM symbols. The authors in [7] analyze the probability of error in detail for the joint beam position tracking and symbol detection system, and show that the probability of error of a maximal ratio combining scheme is minimized if the beam is tracked accurately enough in time. The authors in [8] consider time synchronization schemes for a detector array receiver in a photon-counting channel in deep space optical communications.…”

“…Let us transmit symbol 0 ≤ j < M for an M-PPM scheme. For an EGC receiver that operates on the maximum likelihood principle, we say that a symbol j is detected if Y j > Y i for all i = j, 0 ≤ i < M. Then, the conditional probability of the correct decision is [7] P(C|j…”
