Mohammed Aboud Kadhim, Jameel K Abed, Gailan Abdul Qadir


3GPP LTE is the evolution of the UMTS in response to ever?increasing demands for high quality multimedia services according to users’ expectations. These technologies have been selected for LTE 3GPP. Pilot?assisted channel estimation is a method in which known signals, called pilots, are transmitted along with data to obtain channel knowledge for proper decoding of received signals. This paper refers to channel estimation based on time-domain channel statistics. Using a general  channels model for Stanford University Interim (SUI) Channel Models, the aim of the paper is to find out the most suitable channel estimation algorithms for the existing LTE 3GPP Baseband Transceiver and modified the bit error rate for this system. Starting with the analysis of channel estimation algorithms, we present the Minimum Mean Square Error (MMSE (and Least Square (LS (estimators and compromising between performances under different SUI channel scenarios. Performance of these algorithms has been measured in terms of Bit Error Rate (BER). The bit error rate for a 16-QAM system is presented by methods of Matlab simulation results.

Keywords: LTE 3GPP, MMSE, LS, OFDM, SUI.
