Abstract :
A non-decision-aided (NDA) PLL method, which recovers the carrier phase of QPSK/TDMA bursts without preamble by iterative processing, is presented. The characteristics of the phase detector in the loop are examined and the results show that the NDA PLL exhibits similar performance to a 4th power PLL. The phase error performance was simulated and the results indicate that the proposed NDA PLL is applicable to recovering carrier phase of QPSK/TDMA bursts of an order of 100 symbols or more in length
