ABSTRACT:
In a burst mode communication system bursts arrive at a receiver which must correctly acquire and track carrier and clock phases in order to recover the transmitted symbols. A burst mode receiver is used to recover the clock and carrier phase. The detection of an initiator pulse indicates the presence of a burst signal, and a cross-coupled fractionally spaced digital filter structure is used with a known preamble to perform symbol sampling phase recovery and carrier phase acquisition, and during the normal mode of operation results in a tracking of the symbol and carrier phases.
