Generalised prefix for space-time block-coded orthogonal frequency division multiplexing wireless systems over correlated multiple-input multiple-output channels
Yıldız, Hakan; Acar, Yusuf; Cooklev, Todor; Doğan, Hakan (Inst Engineering Technology-Iet, Michael Faraday House Sıx Hılls Way Stevenage, Hertford Sg1 2Ay, England, 2014-06-12)Space-time block coding (STBC) orthogonal frequency division multiplexing (OFDM) is known to improve the reliability of broadband communication over wireless links. However, this technique suffers from a performance loss ... -
Generalized Prefix Approach for Alamouti Coded OFDM Systems over Gaussian Channels Correlated in Space
Acar, Yusuf; Yıldız, Hakan; Cooklev, Todor; Doğan, Hakan (IEEE, 345 E 47Th St, New York, Ny 10017 Usa, 2014)In this ivorkt, generalized frelix (GP) lbr space time block coded orthogonal frequency division multiplexing (STBC-OFDM) systems is considered in the presence of correlated channel. The 2x2 STBC case, in practice, lead ... -
High-Performance Mimo Ofdm Wireless Systems With Generalized Prefix
Acar, Yusuf; Yıldız, Hakan; Cooklev, Todor; Doğan, Hakan (IEEE, 345 E 47Th St, New York, Ny 10017 Usa, 2013)Consumers require increasing data rates and therefore it is important to develop techniques that increase the spectrum efficiency. MIMO OFDM is a fundamental technology for high data rate wireless systems. Correlation among ... -
Performance Improvement for Correlated 4x4 MIMO-OFDM Systems by Generalized Prefix Approach
Acar, Yusuf; Cooklev, Todor; Doğan, Hakan; Yıldız, Hakan (IEEE, 345 E 47Th St, New York, Ny 10017 Usa, 2013)Antenna correlation limits the multiplexing gain achieved by practical MIMO-OFDM systems and degrades the performance significantly. Recently, investigations are focused to reduce the antenna correlation by the designing ...
