Power Control for MIMO Diversity Systems With Nonidentical Rayleigh Fading
2009
IEEE Transactions on Vehicular Technology
Preserved Fulltext
We investigate the performance limits and associated power allocation problems in a multiple-antenna diversity system with statistical channel information available at the transmitter. ...
The channels are assumed to be independent and non-identically distributed Rayleigh fading. ...
It can be accomplished by using space-time block codes (STBC) or other spreading codes together with appropriate combining at the receiver. ...

We show that a hybrid system robust to different weather conditions is obtained by joint bit-interleaved coded modulation (BICM) of the bit streams transmitted over the RF and FSO sub-channels. ...
An asymptotic performance analysis reveals that a properly designed convolutional code can exploit the diversity offered by the independent sub-channels. ...
In our work, we extend the theory to nonidentical, heterogeneous parallel channels. • Algorithms and computational methods for searching the optimum combination of code and assignment pattern for different ...

We show that distributed space-time trellis coding inherits the coding gain of space-time trellis codes over space-time block codes even in the cooperative setting. ...
The first scheme is called distributed space-time block coding. Depending on the chosen design, it allows for low-complexity coherent, differential, and noncoherent detection. ...
The first scheme that we propose is distributed space-time block coding. De-

In this backdrop, we propose the improper Gaussian signaling (IGS) to mitigate the drastic impact of HWIs and improve the system performance in terms of achievable rate and outage probability. ...
Numerous studies have commenced efforts to model one or the other forms of hardware impairments in the ra- dio frequency (RF) transceivers. ...
The important class of space-time block-codes for MIMO channels i.e., linear dispersion codes is constructed from linear combination of input symbols and their complex conjugates. ...
