Interference alignment based on adaptive eigenmodes in a multiple-input, multiple-output cognitive radio network

Identification of Multiple Input-multiple Output Non-linear System Cement Rotary Kiln using Stochastic Gradient-based Rough-neural Network

Because of the existing interactions among the variables of a multiple input-multiple output (MIMO) nonlinear system, its identification is a difficult task, particularly in the presence of uncertainties. Cement rotary kiln (CRK) is a MIMO nonlinear system in the cement factory with a complicated mechanism and uncertain disturbances. The identification of CRK is very important for different pur...

Multiple Antenna Non-ideal Channel Information Interference Alignment Method in Cognitive Radio Network

Interference alignment scheme, because of non ideal channel, can cause interference to primary user increases, it is worse at the same time the user's transmission rate, aiming at this problem, this paper studies the multiple antenna system is a kind of cognitive radio interference can achieve full multiplexing gain alignment method, analyses the interference alignment method under the conditio...

Modeling of Multiple-Input Multiple-Output Radio Propagation Channels

Multiple - Input Multiple - Output Wireless Communication Systems with Cochannel Interference

To meet the requirement of very high data rates for wireless Internet and multimedia services, multiple transmitting and multiple receiving antennas have been proposed for fourth generation wireless systems. In cellular systems, performance is limited by fading and cochannel interference from other users. Most of the current studies on multiple-input multiple-output (MIMO) systems assume that t...

A Multiple-Input Multiple-Output Cepstrum

This paper extends the concept of scalar cepstrum coefficients from single-input single-output linear time invariant dynamical systems to multiple-input multiple-output models, making use of the Smith-McMillan form of the transfer function. These coefficients are interpreted in terms of poles and transmission zeros of the underlying dynamical system. We present a method to compute the MIMO ceps...
