Abstract :
The performance of satellite crosslinks using differential biphase shift keying (DBPSK) modulation in doubly dispersive channels can be degraded by the time decorrelation of the channel´s impulse response. The performance of these crosslinks is analyzed using computer simulation techniques. The results of simulation work showing the performance of 60 GHz crosslinks in a doubly dispersive channel is presented. A brief characterization of the dispersive channel is provided, as well as a brief description of the simulator. The results show that for every doubly dispersive channel there is a range of DBPSK signaling rates that maximize crosslink performance. However, maximizing crosslink performance calls for some system design tradeoffs
