GOEL,VIVEK. Semi-blind turbo detection for Multiple-input Multiple-output wireless systems. (Under the direction of Dr. Huaiyu Dai) Multiple-input multiple-output (MIMO) techniques constitute the core of future high speed wireless systems. Blind detection in MIMO wireless systems conserves bandwidth and is better suited for use in multiple user scenarios. Since, most of the modern wireless comm...

Multiple-input multiple-output (MIMO) wireless technology in combination with the orthogonal frequencydivision multiplexing (MIMO-OFDM) is an attractive air interface solution for next-generation wireless local area networks (WLANs). Among the various resources in MIMO multicarrier systems the multiplexing rate assignment is related to the rate of transmissions. Here we proposed a new hybrid cy...

With perfect channel state information (CSI) at the receiver and/or transmitter, multiple-input multiple-output (MIMO) wireless systems exhibit a large capacity improvement over their single-input single-output (SISO) counterparts. However, when the MIMO channel is time variant, CSI is either imperfect or unavailable, leading to severe reductions in the available capacity [1]. Although a few st...

multiple input multiple output (mimo) radars are new generation of array radars that employ orthogonal waveforms for their transmit probing signals. despite of several advantages, this strategy results in transmission of uniform power in all angle of array’s viewing field. therefore, possibility of transmit beamforming and achieving coherent processing gain will be lost. many efforts have been ...

Multiple-input multiple-output (MIMO) have been employed in present wireless systems to achieve high data rates within the limited radio frequency (RF) spectrum. MIMO systems make use of multiple transmitting antennas and multiple receiving antennas. The performance analysis of MIMO system over Rayleigh fading channel with ZF receiver is presented. It can be improved by making use of spatial di...

In this paper we describe and analyze a simple but effective algorithm for selecting transmit antennas and their coding-modulation schemes in multiple input multiple output (MIMO) communication systems. The algorithm selects the most suitable antennas among those available at the transmitter by observing the signal to selfgenerated noise ratio obtained, applying pseudoinverse on the MIMO channe...

This paper is concerned with the problem of estimating the multichannel impulse response function of a 2-D multiple-input multiple-output (MIMO) system given only the measurements of the vector output of the system. Such models arise in a variety of situations such as color images (textures), or image data from multiple frequency bands, multiple sensors or multiple time frames. We extend the ap...
