Abstract

We propose a burst frequency synchronization procedure which is based on the usage of single-carrier training data and orthogonal frequency division multiplexing (OFDM) payload modulation. The payload modulation format is similar to the one that is used in the DAB standard, whereas training data are chosen as simple CAZAC sequences. It is shown that the resulting modulation and transmission scheme is suitable for burst transmission and single-burst demodulation. Performance degradation due to synchronization errors is shown to be small.
