Nowadays, MIMO systems are playing an important role in wireless communications. In this paper, we propose a spatial-temporal adaptive MIMO beamforming scheme for single carrier transmission in frequency-selective fading channels with the assumption of perfect channel state information (CSI) at both the transmitter and receiver. The transmit and receive weight vectors for detecting the precedin...

The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems. The proposed algorithm is based on a time domain kernel which is added to the signal of the anten...

CDMA (Code Division Multiple Access) plays an important role in modern wireless communications. MIMO refers to links with multiple antennas at the transmitter and receiver side. CDMA systems combined with multiple antennas is a promising technique, beyond 3G and 4G wireless communications. MIMO provides spatial diversity, which mitigates the fading. The usage of multiple antennas can significan...

This paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (MIMO) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. The agents may have different dynamics and communicate together under a directed graph. A distributed adaptive method is designed for both cases. The structures of the contro...

1. Introduction The multi-input multi-output (MIMO) technique incorporating space-time coding is a candidate for the next generation high performance wireless communication systems. The MIMO technique employs multiple-element antennas to establish spatial subchannels to improve spectrum efficiency. The promised increase in channel capacity by MIMO is possible only if rich-scattering is present ...

Support for a large number of users is required for the next generation wireless access systems and very high channel capacity must be achieved. The Multiuser-MIMO (MU-MIMO) technique has attracted much attention because of its high spectrum efficiency. However, in downlink MU-MIMO, channel state information (CSI) estimation error occurs in a time varying environment and the transmission qualit...
