Interference Cancelling Detectors In OFDMA/MIMO/Cooperative Communications
(2009-09-02)
In this thesis, we focus on interference cancelling (IC) detectors for advanced communication systems. The contents of this thesis is divided into the following four parts:
1. Multiuser interference (MUI) cancellation in ...
Design Of Linear Precoded MIMO Communication Systems
(2009-07-09)
This work deals with the design of MT transmit, MR receive antenna MIMO (Multiple Input Multiple Output) communication system where the transmitter performs a linear operation on data. This linear precoding model includes ...
Coding For Multi-Antenna Wireless Systems And Wireless Relay Networks
(2009-03-04)
Communication over a wireless channel is a challenging task because of the inherent fading effects. Any wireless communication system employs some form of diversity improving techniques in order to improve the reliability ...
Improved GMM-Based Classification Of Music Instrument Sounds
(2009-03-19)
This thesis concerns with the recognition of music instruments from isolated notes. Music instrument recognition is a relatively nascent problem fast gaining importance not only because of the academic value the problem ...
Joint Evaluation Of Multiple Speech Patterns For Speech Recognition And Training
(2009-12-09)
Improving speech recognition performance in the presence of noise and interference continues to be a challenging problem. Automatic Speech Recognition (ASR) systems work well when the test and training conditions match. ...
Blind Detection Techniques For Spread Spectrum Audio Watermarking
(2009-08-13)
In spreads pectrum (SS)watermarking of audio signals, since the watermark acts as an additive noise to the host audio signal, the most important challenge is to maintain perceptual transparency. Human perception is a very ...
Low Correlation Sequences Over AM-PSK And QAM Constellations
(2009-08-13)
Direct-Sequence Code Division Multiple Access (DS-CDMA), over the last few years, has become a popular technique and finds a place in many modern communication systems. The performance of this technique is closely linked ...
Robust Techniques Of Language Modeling For Spoken Language Identification
(2009-07-23)
Language Identification (LID) is the task of automatically identifying the language of speech signal uttered by an unknown speaker. An N language LID task is to classify an input speech utterance, spoken by an unknown ...
Energy Efficient Scheduling Of Sensing Activity In Wireless Sensor Networks Using Information Coverage
(2009-08-19)
Network lifetime is a key issue in wireless sensor networks where sensor nodes, distributed typically in remote/hostile sensing areas, are powered by finite energy batteries which are not easily replaced/recharged. Depletion ...
Cooperative Communication Protocols : Diversity-Multiplexing Gain Tradeoff And Code Constructions
(2009-05-19)
Cooperative relay communication is a promising means of wireless communication in which cooperation is used to create a virtual transmit array between the source and the destination, thereby providing spatial diversity for ...
