Abstract:
In multi-path channels,any change of symbol timing will increase the sensitivity to delay spread for OFDMA systems.In order to obtain optimum performance of systems,the error of symbol timing synchronization should be reduced as much as possible.Currently,most of the symbol-timing-estimation algorithms are based on training sequences.The advantages of these algorithms are that their implementations are simple,and relatively accurate.However,they also need more spectrum resources,and the timing offset should...
