Abstract :
The realization of a frame synchronization scheme represents a critical task in the design process of an OFDM receiver. A loss of orthogonality between the multiplexed subcarriers can result in severe bit error rate degradations. In this paper we compare different OFDM burst synchronization schemes in terms of hardware relevant aspects such as chip area/costs and impact of quantization effects. Furthermore we propose an efficient synchronization algorithm for OFDM burst applications. Simulation results related to a HiperLAN/2 model are provided.
