Burst repetition spreading is a well known method for signal spreading in satellite communication systems. Frequency offsets cause a rotation in the repetition symbols, thus in the de-spreading process the repetitions are coherently combined by correcting their phase rotation. However, in low SNR conditions, conventional methods for phase offset estimation result in a large combining loss. In this paper, we developed a novel approximate Maximum Likelihood estimator for the repetition phase… CONTINUE READING
