Channel estimation based on adaptive neuro-fuzzy inference system in OFDM
Seyman, M. Nuri; Taspinar, Necmi (Ieice-Inst Electronics Information Communications Eng, 2008)In this letter we purpose adaptive neuro-fuzzy inference system (ANFIS) for channel estimation in orthogonal frequency division multiplexing (OFDM) systems. To evaluate the performance of this estimator, we compare the ... -
Channel estimation based on neural network in space time block coded MIMO-OFDM system
Seyman, Muhammet Nuri; Taspinar, Necmi (Academic Press Inc Elsevier Science, 2013)In this study, we propose feed-forward multilayered perceptron (MLP) neural network trained with the Levenberg-Marquardt algorithm to estimate channel parameters in MIMO-OFDM systems. Bit error rate (BER) and mean square ... -
Pilot Tones Optimization Using Artificial Bee Colony Algorithm for MIMO-OFDM Systems
Seyman, Muhammet Nuri; Taspinar, Necmi (Springer, 2013)How to design the pilot tones that are used in channel estimation has a significant effect on the estimation performance. To achieve good performance in least square (LS) algorithm, we propose the artificial bee colony ... -
Radial Basis Function Neural Networks for Channel Estimation in MIMO-OFDM Systems
Seyman, M. Nuri; Taspinar, Necmi (Springer Heidelberg, 2013)Orthogonal frequency division multiplexing (OFDM) combined with multiple input multiple output (MIMO) antennas is one of the promising schemes for high rate data transmission and capacity improvement. However, in these ...
