| Abstract: | A timing synchronization algorithm of orthogonal frequency division multiplexing(OFDM)based on IEEE802.16e was studied.According to the characteristies of the frame structure defined in IEEE802.16e standard,a DSP hardware implementation scheme of timing synchronization subsystem was proposed,and the scheme was implemented by using TMS320C6416 of TI Company.The result shows that this implementation scheme has good performance. |
