Experimental evaluation demonstrates superior channel estimation in MIMO-OFDM systems using near-maximum likelihood time-of-arrival estimation, indicating enhanced wireless reception.
This paper contains a new frequency-domain multi-stream channel estimation technique for communication systems such as MIMO-OFDM. The estimator works by first determining the Time Of Arrivals (TOAs) of each data stream using a near Maximum Likelihood (ML) approach and then solving for the corresponding gains. In addition, this paper presents a training sequence that enables other TOA estimators such as ESPRIT to determine multiple data stream's TOAs. The performance of various channel estimators is compared through simulations and experimental data and the results show that the new TOA estimator has the best overall performance.
