Design of a quick-look decoder for the DSN (7,1/2) convolutional code
Abstract
The decoder proposed for a 1200 bit/s telemetry link that will operate while the TDRSS is relaying the signal from the Galileo spacecraft is discussed. Design parameters and performance figures for the three functions of the decoder: acquisition of node synchronization, generation of the decoded bits, and estimation of channel quality.
