Compensation of undesired effects in MIMO wireless transceivers 2012 http://ezaposleni.singidunum.ac.rs/rest/sciNaucniRezultati/oai/record/1/3463 http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=6348077&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D6348077 M. Čabarkapa M. Božić N. Nešković A. Nešković Đ. Budimir This paper presents compensation of all undesired effects (Power Amplifier (PA) nonlinearity, transmitter and receiver antenna crosstalk, before-PA nonlinear crosstalk, Multiple Input Multiple Output (MIMO) channel fading and crosstalk) in MIMO Orthogonal Frequency Division Multiplex (OFDM) wireless systems. It has been demonstrated that reduced-complexity Crossover Digital Predistortion (CO-DPD) algorithm on transmitter side and Matrix Inversion algorithm on receiver side can suppress almost all undesired effects introduced by transmitter, channel and receiver in 4×4 MIMO OFDM System that can be used in modern wireless system applications. A significant complexity reduction is achieved due to the fact that Digital Signal Processing (DSP) during CO-DPD process on transmitter side is done with real instead of complex numbers. conferenceObject 1 2 IEEE Antennas and Propagation Society International Symposium
