Clock recovery for a DCPSK link in a burst mode TDMA system
Abstract
The paper deals with the performance evaluation of the clock recovery subsystem for a 4-phi DCPSK on-board demodulator for a regenerative satellite system. The overall system performance is evaluated both in the steady-state condition, when timing jitter is caused mainly by data noise, and during the acquisition phase, when interburst transients are the main sources of impairments. Also the effects of interchannel interference are considered and evaluated; the results have been obtained mainly by simulation runs using the TOPSIM simulation package. The conclusions coming out from the study are that the clock recovery subsystem, if properly designed, appears to be a minor source of impairment if compared to other impairing factors.
