Claim One:
1. A device for unwrapping phase samples of a burst signal, each phase sample corresponding to an estimated phase of a pilot-block of the burst signal, the device comprising: circuitry configured to generate a set of predetermined number of vectors, each vector including a predetermined number of phase samples of the burst signal, and each vector being offset from a reference vector by a different phase amount, evaluate a first mean and a first variance of the generated set of vectors, compute a set of unwrapped phase samples of the burst signal by rotating the phase samples of the generated vector having a smallest computed first variance by a first rotation amount, update the generated set of vectors based on a new phase sample, calculate a second mean and a second variance of the updated set of vectors, and differences between a predetermined number of unwrapped phase samples and the corresponding predetermined number of phase samples included in the updated vector having the smallest computed second variance, compute a next unwrapped phase sample of the burst signal by rotating the new phase sample by a second rotation amount corresponding to a median value of the computed differences, append the set of unwrapped phase samples with the computed next unwrapped phase sample by performing a left shift operation, and repeat, the update, the calculate, the compute the next, and the append, until all the phase samples of the burst signal are unwrapped.
