ABSTRACT :

Orthogonal frequency-division multiplexing is a popular method for high-data-rate wireless transmission. OFDM may be combined with multiple antennas at both the access point and mobile terminal to increase diversity gain and/or enhance system capacity on a time-varying multipath fading channel, resulting in a multiple-inp ....etc

ABSTRACT
Fuzzy logic, a relatively new cutting edge technology, is nowadays gaining popularity. Fuzzy control is a practical alternative for a variety of challenging control applications since it provides a convenient method for constructing no-linear controllers via the use of heuristic information. Such heuristic information may come from an operator who has acted as a human in the loop controller for a process. A fuzzy controller emulates human decision-making process. Fuzzy control provides a user-friendly formalism for ....etc

I have to give a seminar on MIMO technologies. I would like to know, where can i get suitable information for that topic. I want to see some sample reports so that i can make it easily.

Thank you in advance.

A voice browser is a device which interprets a (voice) markup language and is capable of generating voice output and/or interpreting voice input, and possibly other input/output modalities. The definition of a voice browser, above, is a broad one. The fact that the system deals with speech is obvious given the first word of the name, but what makes a software system that interacts with the user via speech a browser? The information that the system uses (for either domain data or dialog flow) is dynamic and comes somewhere from the Internet. ....etc

MIMO RADAR SIGNAL PROCESSING:MIMO as a Distributed Radar System
ABSTRACT:

Multiple-input multiple-output (MIMO) radar has been receiving increasing attention in recent years from researchers, practitioners, and funding agencies. MIMO radar is characterized by using multiple antennas to simultaneously transmit diverse (possibly linearly independent) waveforms and by utilizing multiple antennas to receive the reflected signals. Like MIMO communications, MIMO radar offers a new paradigm for signal processing research. MIMO radar possesses sig ....etc

Chapter 1
INTRODUCTION
Recently, the concept of multiple-input multiple-output (MIMO) radars has drawn considerable attention. MIMO radars emit orthogonal waveforms or non coherent waveforms instead of transmitting coherent waveforms which form a focused beam in traditional transmitter based beam forming. In the MIMO radar receiver, a matched filter bank is used to extract the orthogonal waveform components. There are two different kinds of approaches for using the non coherent waveforms. First, increased spatial ....etc

We present a new model for multiple input multiple-output (MIMO) out door wireless fading channels which is more general and realistic than the usual i.i.d. model. We investigate the channel capacity as a function of parameters such as the local scattering radius at the transmitter and the receiver, the distance between the transmit (TX) and receive (RX) arrays, and the antenna beamwidth sand spacing. We point out the existence of pinhole channels which exhibit low fading correlation between antennas but still have poor rank properties and hen ....etc
