Abstract
This article presents a technique for computation of the means and variances of modulation losses for phase-modulated residual carrier communication systems. The emphasis ts on the coherent turnaround ranging signal that operates simultaneously with the data channels (command data channel on the uplink and telemetry on the downlink). Effects of the automatic gain control (AGC) loop on turnaround simultaneous uplink commanding and ranging are considered in the computation of the downlink modulation losses. Finally, algorithms with flow charts for computing the means and variances of the modulation losses for both uplink and downlink are presented.
