Simulation of Time-Domain LMMSE Channel Estimation for MIMO-OFDM Systems using Sliding Window Concept

Geetali C. Bhosle, Shrikrishna D. Patil

Abstract: In this paper, we designed time domain linear minimum mean square estimator for Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems. MIMO-OFDM system undergoes interference due to multiple antennas, channel conditions, noise etc. In order to mitigate these interferences and improve the signal quality at receiver side we use channel estimation techniques. The TD-LMMSE channel estimation technique is used so that the received signal has less error and could be approximated to the transmitted signal. Furthermore, we are using sliding window concept along with TD-LMMSE for MIMO-OFDM and on the basis of simulation results it is observed that the proposed system shows improved results when compared with SISO-OFDM systems.
