![]() ![]() All the numerical results are verified by Monte-Carlo simulations. To show the net diversity gain of a multiple aperture receiver system, BER performances and outage probabilities of MRC and SC multiple aperture receiver systems are compared with a single monolithic aperture with the same total aperture area (same total average incident optical power) for satellite-to-ground downlink optical communications. Bit-error rate (BER) performances for binary phase-shift keying modulated coherent detection and outage probabilities are analyzed and compared for SC diversity using analytical results and for MRC diversity through an approximation method with different numbers of receiving aperture each with the same aperture area. Maximum ratio combining (MRC) and selection combining (SC) techniques are considered as practical schemes to mitigate the atmospheric turbulence. The performances of satellite-to-ground downlink optical communications over Gamma–Gamma distributed atmospheric turbulence are studied for a coherent detection receiving system with spatial diversity. Pertaining to cellular networks, the radio downlink is the transmission path from a cell site to the cell phone. Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored. In the context of satellite communications, a downlink (DL) is the link from a satellite to a ground station.Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.Use these formats for best results: Smith or J Smith.For best results, use the separate Authors field to search for author names.Use quotation marks " " around specific phrases where you want the entire phrase only.Question mark (?) - Example: "gr?y" retrieves documents containing "grey" or "gray".Asterisk ( * ) - Example: "elect*" retrieves documents containing "electron," "electronic," and "electricity".Improve efficiency in your search by using wildcards. The downlink the satellite is transmitting the signal and the earth station is receiving it.Example: (photons AND downconversion) - pump.Example: (diode OR solid-state) AND laser.Note the Boolean sign must be in upper-case. The best satellite internet services offer up to 300 Mbps download speeds, and you can get. Satellite internet is a good option for you if you live in a rural area where cable, fiber, or DSL internet providers aren't available. Separate search groups with parentheses and Booleans. Viasat, HughesNet, and Starlink are the best satellite internet providers.Keep it simple - don't use too many different parameters.
