摘要：

In　this　paper,　two　methods　of　signal-to-noise　ratio　(SNR)　estimation　based　on　the　Secondary　Synchronization　Signal　(SSS)　in　long　term　evolution　(LTE)　system　are　proposed.　The　proposed　methods　utilize　the　subcarriers　carrying　SSS　to　estimate　the　average　signal　power　and　average　SNR.　Performances　are　described　over　Rayleigh　fading　channels.　Simulation　results　show　that　the　proposed　methods　are　robust　over　multipath　fading　channels　with　large　Doppler　frequency.　The　proposed　methods　are　also　simulated　and　analyzed　when　timing　error　exists,　and　the　performance　is　excellent.　©　2012　Springer-Verlag　GmbH.
