ITU recommendations mentioned by Enrico (SA.1742 and SA.1805) base their link budgets on the following papers:<o:p></o:p></span></font></p>
<p class="MsoNormal"><font size="2" color="black" face="Tahoma"><span lang="EN-GB" style="font-size:10.0pt;font-family:Tahoma;color:black">[1] B. J. Klein and J. J. Degnan, "Optical Antenna Gain. 1: Transmitting Antennas," Appl. Opt. 13, 2134-2141 (1974)<o:p></o:p></span></font></p>

<p class="MsoNormal"><font size="2" color="black" face="Tahoma"><span lang="EN-GB" style="font-size:10.0pt;font-family:Tahoma;color:black">Whereas I think everybody agrees with the Tx-gain definition given in [1], the Rx-gain definition provided in [2] may
not be consensual. In particular, the Rx-Gain includes the “losses at the detector”, which makes the Rx-gain depend also on the detection technique and possibly on the turbulence parameter r_0. E.g., the Strehl loss would thus be included in the Rx-Gain. (<a href="http://cwe.ccsds.org/sls/docs/SLS-OCM/Meeting%20Materials/2011_05_Berlin/FSO_LinkBudgetConventions_Proposal_20110324.pdf">As
you know</a>, I personally prefer to avoid the concept of Rx-gain).<o:p></o:p></span></font></p>

<p class="MsoNormal"><font size="2" color="black" face="Tahoma"><span lang="EN-GB" style="font-size:10.0pt;font-family:Tahoma;color:black">Note also that the ITU recommendation P.1814 bases its link budget on the “geometrical attenuation” (which we also call
“free-space coupling loss”) formulated as the ratio of two surfaces. So, ITU seems flexible regarding link-budget formulations.<o:p></o:p></span></font></p>
