  • Abstract
    A new carrier recovery algorithm for bandwidth efficient modulations at low signal-to-noise ratios (SNR) is proposed using only 5 to 10 percent of overhead symbols. It obtains carrier offsets without using conventional phase differentiation, thus avoiding noise enhancement, which is a limiting factor at low SNR, and also does not utilize periodical preambles, which have undesired emissions and probability of false acquisition.
