Artificial neural network based sparse channel estimation for OFDM systems
(Kadir Has Üniversitesi, 2017)In order to increase the communication quality in frequency selective fading channel environment, orthogonal frequency division multiplexing (OFDM) systems are used to combat inter-symbol-interference (ISI). In this thesis, ... -
Power and rate adaptation for MQAM/OFDM systems under fast fading channels
(IEEE, 2012)In this paper the effect of power and rate adaptation on the spectral efficiency of orthogonal frequency division multiplexing (OFDM) systems using M-ary quadrature amplitude modulation (MQAM) is investigated in the presence ... -
SISO - MIMO applications and analysis of visible light communications systems
(Kadir Has Üniversitesi, 2016)Rapid development in technology and increasing necessity to reach information instantaneously saturates RF bands rapidly. Because of that, it can be seen that we are gradually approaching upper limits of the band. It can ...
