| Abstract: | OFDM is extensively used in wireless communication systems for its excellent performance in multipath channel and simple receiver design.Now more and more wireless network coexist under the OFDM framework,which make the multi-mode terminal the solution of multi-network ubiquitous communication.This paper is about the configurable synchronization module of multi-mode terminal,and focuses on the integration of timing and frequency offset estimation.Then it proposes the conception of configurable multi-mode synchronization system which supports WLAN,LTE and DVB-T systems. |
