Comparison of preamble structures for burst frequency synchronization

Two types of repetition preambles are compared concerning frequency synchronization in burst transmission. A near–optimum frequency estimation algorithm with scalable lock–in range is proposed in conjunction with a reduced–overhead synchronization preamble, the so–called sandamble. Even though the fundamental ideas are independent from the specific modulation scheme, we study the algorithms in an Orthogonal Frequency–Division Multiplexing (OFDM) system.
