Celandroni N. Unique word detection false alarm probability in TDMA systems. Internal note CNUCE-B4-92-011, 1992.
 
 
Abstract
(English)
The unique word (UW) detection false alarm probability for TDMA systems adopting B/QPSK modulation schemes is studied in detail. The study is focused on digital communications via satellite, even though most of the results have a more general validity. Recalls of the miss probability are also given for convenience and general criteria for dimensioning the UW length and the detection threshold are also given. In particular a typical QPSK case adopting a four element 12 bits UW with carrier phase ambiguity removal is computed and graphs are provided. The system designer is warned against dangerous choices which can be easily avoided.
