Pilot Tones Optimization Using Artificial Bee Colony Algorithm for MIMO-OFDM Systems
(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
(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 ...
