LTE CE(Channel Estimation)

 

       LTE physical Layer will provide peak data rate in uplink up to 50 Mb/s and in downlink up to 100 Mb/s with a scalable transmission

       bandwidth ranging from 1.25 to 20 MHz to accommodate the users with different capacities. For the fulfillments of the above

       requirements changes should be made in the physical layer (e.g., new coding and modulation schemes and advanced radio access

       technology). In order to improve the spectral efficiency in downlink direction, Orthogonal Frequency Division Multiple Access (OFDMA),

       together with multiple antenna techniques is exploited.

 

      Accurate transmission and estimation of channel statistics affected by a high Doppler spread is one of the main issues of concern

      in mobile communication systems.
