In this paper, a new carrier synchronization loop for high-order QAM signals has been proposed in which a blind source separation algorithm for carrier phase tracking is used as phase estimator in feed-back configuration. When used for large constellation schemes, simulations show that the proposed solution achieves better phase tracking and improves performance of the carrier phase tracking loop...
We describe in this paper the solutions adopted to fulfill the MIL-STD-188-110B standard HF modem requirements. We present the designs details of all the blocks of the standard such as channel encoding/decoding, matched filtering, digital modulation/demodulation, synchronization, and equalization. We deal also with channel modeling and provide performance analysis of the developed chain of communication.
