Determination of the cyclic prefix length in MC-CDMA using firefly algorithm
(Pamukkale Univ, 2017)
Cyclic prefix is utilized to prevent intermho) interference and inter currier interference M multi currier communication,systems such us multi -carrier code division multiple access that provides high speed data transmission, ...
Channel estimation based on neural network in space time block coded MIMO-OFDM system
(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
(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 ...
