Book excerpt: Describes development of an algorithm for synchronization to phase shift keying and quadrature amplitude modulated signals for which little a-priori information is known, in the presence of timing and carrier frequency offsets. Some simplifications of the synchronization problem have been made so that this algorithm could be characterized independently of several variables. The algorithm is based on minimizing an objective function which is sensitive to the delay and frequency offsets. Using two one-dimensional searches in the delay-frequency plane, the algorithm attempts to find the optimum values which maximize the objective function. Simulation results are presented to illustrate the performance of the algorithm and to indicate areas where improvements can be made.
