Through a unified framework, it emphasizes how propagation mechanisms such as space-time frequency correlations and coherent components impact the MIMO system performance under realistic power constraints. Combining a solid mathematical analysis with a physical and intuitive approach to space-time coding, the book progressively derives innovative designs, taking into consideration that MIMO channels are often far from ideal.The various chapters of this book provide an essential, complete and rMIMO systemsWireless communication systemsMIMO systems.Wireless communication systems.621.384Oestges Claude971994Clerckx Bruno1579013MiAaPQMiAaPQMiAaPQBOOK9910784614103321MIMO wireless communications3858771UNINA
