Performance of CP-FREE ST-BC MIMO-OFDM System Under IQ-Imbalance in Multipath Channel [PDF]
[[abstract]]The CP-free MIMO-OFDM system is considered to be an alternative to improve the spectral efficiency of the CP-MIMO-OFDM system. In this paper, we investigate the performance of the CP-free ST-BC MIMO-OFDM system under the effects of non-linear

MIMO-OFDM wireless communication systems
, 2021 Wireless communication systems suffer from fading and these fading characteristics have arandom nature. In this thesis, mobile fading channel characteristics are adressed, and frequencyselective fading channels are concerned for mitigation. Space-time block codes are proposed fordiversity, and to achieve reliable communication rates under slow and flat
