Abstract Rapid carrier and bit-timing synchronization are essential in burst mode communication systems. A new algorithm for fast synchronization in a bust mode OQPSK receiver is proposed in this paper. The algorithm is based on a specific bit-pattern preamble, which allows total decoupling of the carrier phase and bit-timing phase and thus permits direct, simultaneous estimating of the reference parameters by open-loop approach. It is shown that the algorithm achieves a significantly agile carrier and bit-timing recovery. The algorithm is applicable to satellite communication systems, mobile communication systems etc.
