Consideration of 120-Mbit/s burst-mode adaptive threshold detection with estimated sequence processor development
Abstract
The adaptive threshold detection with estimated sequence (ATDES) processor is a practical version of maximum-likelihood-sequence detection (MLSD). A 60-Mbit/s continuous-mode ATDES processor has been developed and tested via an Intelsat IV F-4 and Paumalu earth station link. Experimental data obtained to date from Intelsat V 120-Mbit/s QPSK channel transmission tests and 60-Mbit/s ATDES testing indicate that an improvement of about 2 dB in Eb/No at a BER of 10 to the -6th could be achieved by a 120-Mbit/s burst-mode ATDES processor.
