The long term evolution of evolved universal mobile telecommunications system terrestrial radio access, is based on OFDM techniques owing to its inherent flexibility and attractive implementation potential. This paper addresses the issue of time synchronization which is imposed severely challenges particularly in the downlink of LTE systems and the means of time offset estimation exploring different...
This paper deals with the minimum mean square error estimation (MMSEE) of spatial channel model (SCM) in the Third Generation Partnership Project (3GPP) based on orthogonal frequency division multiplexing (OFDM) system. In particular, we focus on MMSEE on the basis of maximum likelihood estimation (MLE). Since statistical information is the critical element of MMSEE, we derive the generation of coefficients...
Orthogonal frequency division multiplexing (OFDM) is the modulation scheme of choice for digital video broadcasting-handheld (DVB-H) which is required to operate under high mobility conditions resulting in significant Inter-Carrier Interference (ICI). Under these conditions, the conventional one-tap per subcarrier channel estimation and equalization is suboptimal since it does not account for ICI...
