MDCT Domain Enhancements For Audio Processing
(2011-05-10)Modified discrete cosine transform (MDCT) derived from DCT IV has emerged as the most suitable choice for transform domain audio coding applications due to its time domain alias cancellation property and de-correlation ... -
Guessing And Compression : A Large Deviations Approach
(2011-04-01)The problem of guessing a random string is studied. It arises in the analysis of the strength of secret-key cryptosystems against guessing attacks. Expected number of guesses, or more generally moments of the number of ... -
A Filterbank Precoding Framework For MIMO Frequency Selective Channels
(2011-02-28)Wireless systems with multiple antennas at both the transmitter and receiver (MIMO systems) have been the focus of research in the recent past due to their ability to provide higher data rates and better reliability than ... -
Process Variability-Aware Performance Modeling In 65 nm CMOS
(2011-02-25)With the continued and successful scaling of CMOS, process, voltage, and temperature (PVT), variations are increasing with each technology generation. The process variability impacts all design goals like performance, ... -
Rate-Distortion Performance And Complexity Optimized Structured Vector Quantization
(2011-02-09)Although vector quantization (VQ) is an established topic in communication, its practical utility has been limited due to (i) prohibitive complexity for higher quality and bit-rate, (ii) structured VQ methods which are not ... -
Performance Analysis Of Multiuser/Cooperative OFDM Systems With Carrier Frequency And Timing Offsets
(2011-02-03)Multiuser and cooperative orthogonal frequency division multiplexing(OFDM) systems are being actively researched and adopted in wireless standards, owing to their advantages of robustness to multipath fading, modularity, ... -
Belief Propagation Based Signal Detection In Large-MIMO And UWB Systems
(2011-02-03)Large-dimensional communication systems are likely to play an important role in modern wireless communications, where dimensions can be in space, time, frequency and their combinations. Large dimensions can bring several ... -
Low-PAPR, Low-delay, High-Rate Space-Time Block Codes From Orthogonal Designs
(2011-02-03)It is well known that communication systems employing multiple transmit and multiple receive antennas provide high data rates along with increased reliability. Some of the design criteria of the space-time block codes ...
