Abstract

In SC-FDE (single carrier with frequency domain equalization) systems, timing offset brings ISI (inter-symbol interference). In order to obtain better timing precision in multi-path, a new timing offset estimation method applied to SC-FDE systems is proposed based on the analysis of Schmidl & Coxpsilas and Minnpsilas algorithms. By designing new training symbols and introducing corresponding calculation method, performance of timing synchronization can be improved obviously. Finally, three algorithms are compared by computer simulations and the comparison results confirm the effectiveness of the proposed algorithm.
