Abstract


IEEE802.16e OFDM system synchronization technology . First introduced the physical layer of the IEEE 802.16e OFDM system . On this basis , the IEEE 802.16e OFDM frame synchronization , symbol synchronization and carrier frequency offset estimation , conduct analysis and research . Studies the frame synchronization using Schmidl Cox delay algorithm analysis and propose two improvements . Coarse symbol synchronization in the study , using the filter principle of conventional coarse symbol synchronization method has been improved, to reduce implementation complexity . In a long analysis of the time-domain carrier synchronization , improved short training sequences combined carrier frequency offset estimation method . Integer multiple carrier frequency offset estimation , a long training sequence to estimate the improved method . Complete Matlab simulation of IEEE 802.16e OFDM frame synchronization , coarse symbol synchronization , time domain Carrier Frequency Offset Estimation , select the appropriate program , using Quartus FPGA hardware circuit design .
