Abstract
The characteristics of the decision feedback carrier recovery loop (DFL) fo r conventional QPSK signaling is evaluated experimentally through measureme nts of the carrier-to-noise ratio of the regenerated carrier, lock range, a cquisition waveforms and bit error rates. The results show that the DFL har dly exhibits inferiority to the ideal synchronization by designing the loop natural frequency adequately small. The DFL is shown superb in carrier tra cking.
