We analyze the impact of imperfect channel state information at the transmitter and receiver (CSITR) on the achievable diversity gain in multi-input multi-output (MIMO) fading channels with joint rate and power control. With rate control only, we consider the system with and without a minimum ...

Specifically, apparent diversity gain (or simply diversity gain) is the SNR gain (indB) of using two coupled elements compared to using the best coupled element alone (in other words, the element with the stronger average received signal). ...
We also achieve simplified calculations for the performance at high SNR to gain insights regarding the factors determining the performance in fading. It is shown that the multiuser MIMO systems can achieve a full diversity order. The achieved results provide an analytical framework for the assessment...
Coherent and Non-Coherent Data Detection Algorithms in Massive MIMO Massive MIMO increases the spatial multiplexing gain and the data rate by adding an excessive number of antennas to the base station (BS) terminals of wireless communication systems. However, building efficient algorithms able to decod...
Computer simulation showed that a 2 ×2 MIMO system with a 2-element RF-AAA implemented using Alamouti's scheme provided an array and a greater diversity gain and lower bit error rate (BER) performance than a 2 × 4 MIMO system with maximum likelihood decoding (MLD) in both low and high...
and equal-gain combining schemes. Various transmit diversity schemes are described, depending on the availability of channel state information on transmitter side. The most of the chapter is devoted to wireless and optical MIMO techniques. After description of various wireless and optical MIMO models,...

In this letter, the different performance in terms of diversity gain and multiple-input multiple-output (MIMO) capacity of the same linear MIMO array in different nonisotropic propagating scenarios is demonstrated with a reverberation chamber (RC) for the first time. This could be useful for ...
