single carrier fdma

hello everyone,
i need some background on SC-FDMA and how it is different from OFDMA.

and any material related to LTE ( long term evolution ) will be helpful.
 

hello guys , can anyone help me out..
 

do google search on LTE..u'll find a lot of materials ..
 

In LTE OFDMA is used in Downlink.OFDMA having High PAPR.signals with high PAPR requires highly linear power amplifiers inorder to avoid excessive intermodulation distortion so,amplifiers must be operate with a large backoff from its peak value.High PAPR is particularly critical for uplink trasmissions because of power constraints at UE.

SC-FDMA is used in uplink.SC-FDMA having low PAPR.Because of low PAPR, SC-FDMA is well suited to uplink.
