Abstract
Adaptive data rate (ADR) functionality was added to the Mars Reconnaissance Orbiter (MRO) Electra software-defined radio (SDR) via software and firmware uploads to its modem in October 2011. An integral part of ADR is the symbol signal-to-noise ratio (SNR) estimation algorithm. The Whole Symbol Moments SNR Estimator (WSME) algorithm has been developed for ADR control and was included in the October 2011 upload. It is the subject of this article. The WSME architecture is described and performance results are presented via analysis, simulation, and data from an inflight MRO test on March 5, 2012.
