Adaptive MIMO-OFDM Channel Estimation of Super Resolution Approach Utilizing Spatial and Temporal Correlation and TTOP

Abstract

This paper provides adaptive technique for the channel estimation of MIMO-OFDM. Generally there are a lot of methods for channel estimation of OFDM as well as MIMO OFDM. In this paper I first described about the latest MIMO OFDM channel estimation which is super resolution approach that explores spatial and temporal correlation of MIMO-OFDM. I then designed conventional Time domain training based orthogonal pilot (TTOP). I then compared the performance of two channel estimation schemes i.e. 2 D graph between the SNR vs. BER.I generated the performance graphs for different MIMO OFDM antenna pairs for above two. And finally I propose the combination of two techniques which is used in Adaptive way given much better results than previous channel estimation techniques and it will better utilize resources much efficiently.
