Abstract
This article describes the breadboard Advanced Receiver II (ARX II) that is currently being built for future use in NASA’s Deep Space Network (DSN). The hybrid analog/digital receiver performs multiple functions including carrier, subcarrier, and symbol synchronization. Tracking can be achieved for residual, suppressed, or hybrid carriers and for both sinusoidal and square-wave subcarriers. Other functions such as time-tagged Doppler extraction and monitor/control are also discussed, including acquisition algorithms and lock-detection schemes. System requirements are specified and a functional description of the ARX II is presented. The various digital signal-processing algorithms used are also discussed and illustrated with block diagrams.
