Performance Evaluation of CFO Estimation Algorithm for the Downlink of 3GPP LTE

چکیده
Abstract::LTE is a new standard towards 4 generation in LTE OFDM is used as the basic multiple access technique. OFDM is very sensitive to Synchronization error in from carrier frequency offset because it can cause due to Doppler Shift and frequency mismatch and inter carrier interefernce which results in CFO. In this paper, we present algorithms for determining carrier frequency offset (CFO) for the downlink of 3GPP LTE. Three CFO estimation techniques, cyclic prefix (CP) based technique, Moose algorithm and Classen algorithm are presented in th is paper. The estimation techniques cover both time and frequency for OFDM system. Simulation of this CFO estimation algorithm is examined.

متن کاملPerformance Evaluation of Differential Modulation in LTE - Downlink
This paper evaluates the performance of differential modulation applied to the 3GPP UMTS Long Term Evolution downlink. With differential modulation, reference symbols for channel estimation are no longer necessary, thus increasing the potential maximum spectral efficiency. We present two basic modulation schemes and compare their performance to the coherent detection employed in Long Term Evolu...

متن کاملComparative Evaluation of Fractional Frequency Reuse (ffr) and Traditional Frequency Reuse in 3gpp-lte Downlink
3 Generation Partnership Project Long Term Evolution (3GPP-LTE) is focusing towards aggressive frequency reuse i.e. reuse of 1 so that we can get maximum number (all available spectrum) within a cell. Now, the major hindrance is co-channel interference which increases dramatically due to nearby adjacent co-channel cell and most especially for cell edge users. Traditional frequency reuse concept...
