An analysis of MIMO antenna system in the development of LTE (Long Term Evolution) terminal and the compensation of user’s induced loss is presented in this paper. MIMO wireless systems have antenna arrays at both the transmitter and receiver terminals. Multiple input multiple output (MIMO) technology has been regarded as a practical approach to achieve significant increase of wireless channel ...

Multiple-input multiple-output (MIMO) systems are well known as a technique which allows increasing the throughput of a radio link and overcoming the effects of multipath fading. However, the integration of MIMO systems into the standards of wireless networks is slow, as there are numerous problems still unsolved. This PhD thesis deals with MIMO systems in slow and fast varying radio channels. ...

MIMO systems have raised a lot of interest in the recent years. The radar community pointed out the multiple advantages of MIMO systems such as diversity gain for target detection, angle of arrival and Doppler estimation. Coherent processing also allows super-resolution for target localisation. We explore in this paper broadband MIMO sonar systems. In the current literature, the channel matrix ...

Non-orthogonal multiple access (NOMA), as the newest member of the multiple access family, is envisioned to be an essential component of 5G mobile networks. The combination of NOMA and multiantenna multi-input multi-output (MIMO) technologies exhibits a significant potential in improving spectral efficiency and providing better wireless services to more users. In this article, we introduce the ...

Multiple-input multiple-output (MIMO) wireless communication systems employ multiple transmit and multiple receive antennas to obtain significant improvement in channel capacity. However, the capacity is limited by the correlation of subchannels in non-ideal scattering environments. In this paper, we investigate MIMO systems that use antennas with dissimilar radiation patterns to introduce deco...

There is an increasing demand for high data transmission rates with the evolution of the very large scale integration (VLSI) technology. The multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) systems are used to fulfill these requirements because of their unique properties such as high spectral efficiency, high data rate and resistance towards multipath propag...

CDMA and MIMO-CDMA systems using RAKE receivers are heavily limited by selfand multiple-accessinterference. Linear equalization is a means to remove this interference, however it is often not practical due to the enormous complexity, especially in the MIMO case. This paper presents an approach to greatly reduce the complexity of linear MIMO equalizers. It discusses the complexity reduction of t...

This letter introduces a joint design method for uplinkdownlink multiple-input multiple-output (MIMO) relay communication systems in which the source nodes transmit information to the destination nodes with the help of a relay. We propose a signal forwarding schceme based on the minimum mean-square error (MMSE) approach in uplink relay systems. Exploiting the duality of relay systems, we also p...

This paper investigates adaptive blind equalization for multiple-input and multiple-output (MIMO) channels and its application to blind separation of multiple signals received by antenna arrays in communication systems. The performance analysis of the CMA equalizer used in MIMO channels is first presented. Our analysis results indicate that for the MIMO FIR channels satisfying certain condition...
